Do this before the call. It takes about 2 minutes.
If you see a cloud with an arrow instead of Get, you had Zoom before. Tap the cloud.
At the time you agreed on.
Zoom may show a screen about its terms or ask you to sign in. You don't need to sign in. Tap I Agree or Join a Meeting, never Sign Up.
The first time, your iPhone asks a few questions about Zoom. They pop up one at a time.
Zoom may then show you your own face with Join with Video and Join without Video. Pick either one.
Don't see any buttons? Tap the middle of the screen once. Zoom hides its buttons after a few seconds.
Wait until your helper asks for it. Then three taps.
Not there? Tap More (โขโขโข) and look for Share in that list.
Leave the Microphone button under it alone. Your helper can still hear you either way.
Zoom keeps running in the background, so you can still talk. Don't close Zoom.
Just use your phone the way you normally would.
When your helper says you're done, or any time you want. You're in charge.
Another way: open Zoom again and tap the red Stop Share button.
Say goodbye first. Your helper will close the call too.
If your helper ends the call first, Zoom says the meeting has ended. Tap OK. You're done.
Deleting Zoom doesn't touch Calendar Catcher or anything in it.
