Meet fails to access the USB webcam when using Brave browser

Hi,
meet does not recognize my webcam when using the browser “Brave”. Works well with “Firefox” and “Chromium”.
The webcam : Logitech HP Pro Webcam C920 (046D:0892) connected to an USB port.
OS : Ubuntu 18.04 LTS
Hope this helps.
Regards

Brave works, Vivaldi too. Both need some “help” to detect the hardware by clicking the gear-icon in Jitsi

Hi,
many thanks for your answer.
As a matter of fact, the “help” you suggested seems to be not sufficient :
the settings/Devices section shows that the camera has “permission not granted”. However in Settings/Privacy and security/Site settings the permission to use camera and microphone is set for the site meet.jit.si.
Thanks for your help.
