Anyone else uses Signal for desktop?

I do it for convenience while on Linux, but i was wondering how much of an attack vector would that be in layman’s terms. So assuming that you’re running the latest stable kernel and updates and have taken some “precautions” such as a completely Gapps-free phone… what’s the real risk (if any… but i doubt that somehow) of using the desktop binary linked to your phone?

Thanks!
