PC & Steam Deck logged in same network, how to transfer games? (not stream!)

There is only a green Transfer button (where usually is Play). Is this a snap package limitation (or a bug) that the actualy TRANSFER functionality (not using Valveś servers) does not appear?

The Steam snap used is the latest / edge so the functionality should be there AFAIK. Did this work formerly with the deb package, if anyone knows? Or what is the issue here?
