Integrated webcam not detected Linux 20.04

Hi,

The webcam of my latitude 9420 is not detected by Ubuntu 20.04.

It works fine on windows (I run dual boot) and is checked in the bios.

Running cheese gives me "no device found" and the following errors:

"

cheese-application.vala:214: Error during camera setup: No device found

(cheese:12783): cheese-CRITICAL **: 11:27:29.977: cheese_camera_device_get_name: assertion 'CHEESE_IS_CAMERA_DEVICE (device)' failed

Any help is very welcome.

Thanks!
