I'm saying this based on my various experiences with different people.
So what I'm requesting is to hide personal details such as Email address from the Settings app and any other personal data that could be shown on the screen, when user is letting someone else view their screen.
this can be like Streamer mode in Discord or Streamer mode in Sea of Thieves, where personal data, usernames etc. are hidden from viewers.
this will be very useful and give people peace of mind when letting someone else help them.
