@HistoPol @smallcircles To be honest I have no idea if Threema will work? I don't use android anyone since few years. Btw.. This app is open source or not?
I think better solution in such case can be Session, SimpleX, or something similar to them both. They can be normally used on for example SailfishOS with android api enabled. They also have a cli and desktop versions as well for many operating systems.

Threema "works", if you mean technically. yes. There is also a desktop client.
The app source code is available: (unfortunately on github) https://github.com/threema-ch/threema-android
As to whether it "works" socially, there is an extra barrier to trying to move your network there, which is that each user has to buy a license (for less than the price of a beer in many countries) and this seems to be a huge barrier for most people who prefer their chat apps to be "free" 😉
