I would not trust such an app.
Trusting any 3rd party means of logging into your Steam account puts it at risk. Most of those games would never work anyways because of their need for a certain GPU. Even if emulated a $1500 S25 Ultra is not going to have powerful enough specs for many PC games.

Be better off just doing it the streaming way through Steam Link.

What I used to do was rent a workstation with cloud access. It's not much $ and you'll have a dedicated PC with specs such as i7 with 4080 or better CPU/GPU and access that PC online and install games to it natively and stream them to your phone/tablet

I am moving the files to my PC and Steamdeck, other games like Balatro run fine from my understanding.

I imagine the opensource version would be easier to register as malware since the code is public.
