Fetch Telegram Post's views with Google Apps Script - google-apps-script

Question

I'm trying to fetch this number:
Tested this Telegram post:
https://t.me/s/google_sheets/393
I want to do it with a script. Interesting, it was possible for me to achieve this with a formula:
=INDEX( REGEXEXTRACT(SUBSTITUTE(QUERY(FLATTEN(IMPORTDATA("https://t.me/s/google_sheets/393")),,2^99),CHAR(10),), "(.*tgme_widget_message_views"">)(.+)(<\/span><span class=""copyonly"".*)"),2)
This is the script I've tried:
function GET() {
var reg1 = /tgme_widget_message_views">(.+)<\/span><span class="copyonly"/i;
var response = UrlFetchApp.fetch('https://t.me/s/google_sheets/393').getContentText();
var match = response.match(new RegExp(reg1))[1];
Logger.log(match); // 13.4K, expected: 11.2K
}
It gives me the wrong result. I'm willing to do the work with a script because I want an afficient way of fetching multiple URLs at once. The formula will crash in this situation.
My script gives me the wrong result, it may be the number for other Telegram post (https://t.me/google_sheets/374 ), I'm not sure.
Please help me to resolve this issue.

Since the one you are looking for is that specific post and not the others, you may want to limit what you are searching for by appending the id of the post at the end of your regex. Thus we are sure we are looking just until post id 393. As you can see, I added .+google_sheets\/393 in your regex.
function GET() {
var reg1 = /tgme_widget_message_views">(.+)<\/span><span class="copyonly".+google_sheets\/393/i;
var response = UrlFetchApp.fetch('https://t.me/s/google_sheets/393').getContentText();
var match = response.match(new RegExp(reg1))[1];
Logger.log(match); //11.2K
}
