I have the same issue with my work laptop.
My keyboard use bepo key, but bepo need to be activated on windows, which I can’t do. I’ve tried to use azerty keys but it was a real pain to setup. I gave up using bepo on this computer, but if you find a solution I’m interested !
I just tried Unexpected keyboard, it’s easy to use and open source : https://github.com/Julow/Unexpected-Keyboard you can find it on F droid
