Prevent previewing camera images during distribution mode or screen sharing (Translated by DeepL)

Happening was that while in delivery mode or sharing a screen, the user accidentally pressed the button to turn on the camera, causing the video to be previewed and the facial image to be delivered.
If the "turn on camera" button is clicked in distribution mode or when the screen is shared, we would like to see the camera preview after confirmation by the user.
