Execution on Add-on of Google Sheets throws PERMISSION_DENIED error - google-apps-script

Question

We published an add-on in the Google Marketplace. It works on Google Sheets.
Its written in Google Apps Script, the fact is when we are on the developer account it works perfectly, but when we install it on another accounts
some functions doesn't work (the ones we assign to images on the sheets), on the project execution we get time 0s and in the cloud logs we get the PERMISSION_DENIED error and we don't know why is this happening.
Since the functions to generate the sheets are working well and are on the same script.
Here we have a video reproducing the error:

And here is also the JSON of the error in Cloud log explorer

Thanks in advance for your help
We tried changing the visibility of the add-on, also tried to share the spreadsheet where the main code was (This worked but we dont want to do it this way since we already published and verify the add-on).
The expected behaivour is to be able to run the same functions of the code in any spreadsheet that has the add-on installed.
