In addition to my answer to your original request, I can inform about stuff related to WhatsApp.
You can use WhatsApp on a Matrix server with a bridge. You can either selfhost or find a server which has the WhatsApp bridge.
There is also Beeper - now acquired by Automattic (WordPress, …) - which is a company matrix server with many bridges (they employed the person developing most of them). You can use a FOSS matrix client like Element X or their own client which is not FOSS but requires far fewer permissions than the WhatsApp app

Yeah that a good idea! Will look into it . Must get some self hosting going :)
I think you can deploy Matrix with Yunohost, which is very convenient as a first self hosted server
