ThinOS 9.1 Webcam redirection only works after opening peripherals menu

We are using Wyse 3040 with ThinOS 9.1.6 and have the following scenario :

The webcam connected to our wyse is a Microsoft Lifecam HD-3000.

When first connecting the RDP session to our Windows 2019, Teams does not see any device connected.
If we open the Dell wyse peripheral menu, disconnect our current RDP session and reconnect it, Teams now sees the webcam and function properly.

I tried playing with forced redirection, but nothing seems to solve this.

This manual step can function as a workaround, but is very tedious.
Did you encounter this problem and did anyone manage to solve it ?
