How to add a custom menu for google drive - google-apps-script

As a part of project requirement I need to add a custom menu (context menu) to the google drive right click options.
As per my research google app script can help for creating a custom menu for google docs, google form and google sheet. However I haven't yet come across a way to add a custom menus for google drive.
I cannot use chrome extension as I need it to be all browser compatible.
Any ideas if it's even supported and possible.
Any help is appreciated!

Eventually I had to integrate an app with "Open With" option in Google Drive.
Apparently, context menus are not supported in Google Drive.

You cannot add custom context menus in Google Drive. The custom menus you read about in Docs, Sheets, etc are added in the menubar at the top of the editor, not into the right-click menu.

Google Script - What is the name of this dialog panel?

I am working on University project that would benefit from google forms automatization. I am struggling to find any information how to code that side dialog (marked in blue circle) in Google Forms editor. I would be thankful for linking with any documentation/tutorial how to model that side dialog.
The dialog is created using Google Apps Script to extend Google Forms. You can read about G-Suite Add-ons here and specifically about Forms Add-ons here. I believe the specific Add-on in your screenshot is this.

Can I create a top level menu in a Google Slides add-on?

We are developing a Google Slides add-on and we need to add some custom top-level menus. The documentation on https://developers.google.com/apps-script/guides/menus says:
Scripts that are published as add-ons for Google Sheets, Docs, or Forms cannot create top-level custom menus.
But when I installed the publicly available Poll Everywhere for Google Slides add-on, it added the Poll Everywhere menu as a top-level menu for all documents. How could that be possible considering the quote above?
Poll Everywhere for Google Slides is not an Apps Script add-on, it's a Chrome extension.

How to show images on text hover in google docs addon

I am new to google docs Add-ons. I am working on an add-on in which I need to show set of image on text hover like tooltip in html
I did not find a way to implement this after hours of googling. please help.
This is not possible.
The above because the Documents Service of Google Apps Script doesn't include "on hover" event / trigger or something similar
The only way is by using a dialog or sidebar and they can only be launched by clicking on a custom menu or by using google.script.run on a previously opened dialog / sidebar.

Custom sidebar addon for Google Docs

I am trying to write a simple add-on for Google Docs. It basically a list of items I want to have visible on the side when I am using Docs. I followed this simple tutorial.
I don't want to publish such a simple add-on unnecessarily. Is there a way that I could use it just within my Google Docs without publishing it ?
If you've just copied the sample code into your document's script, it already works there. To activate the script you have to reopen the document, then in the menus at the top click Custom Menu -> Show sidebar.
You only have to publish a script if you want to share your add-on with other users.
If you still have problems, take a look at Add-on Quickstart. It describes add-on creation process in details.

How do I get the Script Manager selection to display under the Tools menu item in a Google Sheet?

I'm new to google sheets and scripts and have been trying some of the tutorial on extending sheets. I've noticed that the tutorial demo Sheets have a Script Manager selection under the Tools menu. When I create my own Sheets and related scripts and function, however, I do not get a Manage Scripts selection in the Tools menu.
Why is this? How do I get the Manage Scripts selection in the Tools menu?
Thanks in advance.
This menu item was in the old version of spreadsheets, it disappeared in the new version you are using.
