Ubuntu 20.04 fvwm and translucency

Hi All,
I am using fvwm as my favourite window management system and I would like to achieve total independence, I managed for most parts except for translucency.
You might think it is just for show but i noticed that it affects screen sharing with Team and Zoom, where there should be a layer on top of the screen for annotations, and that, at the moment appears black.

I managed in the past to trigger that, via the patch, but that was 10 years ago and now I do not anymore, I am really at my wits ends and I would love for someone to help!

I am sure that it can be a trigger or something but I just do not know what to do,

Code:
mau*~lsb_release -a

I May have found the answer:
I am now using compton that helps a lot with translucency and for the backgroung manager (wallpaper)I use nitrogen
They both work really well!
