Pass Bluetooth or USB direct to Proton game?

Hi all,

I'm going to try getting Zwift (a game that connects to Bluetooth, WiFi, or ANT+ bike trainers) running in Linux.

I'm pretty sure I can do this with my trainer since mine supports WiFi connectivity, but am curious as to if I could make it work with trainers that only support BT or ANT+.

I've previously done stuff like USB and PCI pass-through with KVM, but is this possible with Steam and Proton?

Thanks.
