BetterTouch not activating in some apps and programs where it's most needed

Looks like Bettertouch doesn't work in google docs and some apple apps on the Mac, when writing documents. How possible could you integrate this to also work there?

It's working in Google Docs as well, what are you trying to do?

It is just not working. I use the BT every day working everywhere but precisely on google docs online in Chrome, it does not work. I am humbly asking you to take a look at it.
I am using chrome Version 95.0.4638.69, an up-to-date MacBook Pro OS Monterey vs. 12.0.1 (21A559). Every app or software I have in my system is very uptodate.

I configured the middle mouse to bring up my dictionary and yes this configuration works very well in all programs except in Chrome Google Docs. That is what I am trying to do.
