PC: Surface Pro 6
OS: Ubuntu20.04

困っていること
Zoom等のアプリでSurface本体の内蔵カメラを利用したいのですが、Zoomにはカメラを認識してもらえず、Webで調べてみても原因がわかりません。（というより読んでも何を言っているかほとんど理解できません…）

試したこと
①libwebcam0、guvcviewをインストールしてguvcviewを起動してみたところ、"no video device found"とエラーが出ました。デバイスの一覧表示にはなぜか"Intel IPU3 CIO2"が4つ並んでいました。

②参考になるかわかりませんが、以下に試したコマンドと実行結果を載せておきます。
$ v4l2-ctl --list-devices
Intel IPU3 CIO2 (PCI:0000:00:14.3):
    /dev/video0
    /dev/video1
    /dev/video2
    /dev/video3

$ v4l2-ctl -d /dev/video0 --info
