Hi. I'm using Zoom, on an Iphone 14 PRO MAX, running IOS 17.02. I have an external keyboard linked to my phone, via Bluetooth. Is there a set of keystrokes I can use, to mute/unmute, turn video on and off etc? When I use the touch screen, Voiceover is not reliable on focusing on the correct buttons and I often have a lot of swiping to do, so going to try with my external keyboard. Also, is there a way to silence announcements of people posting messages during a call, as well as announcements of people joining and leaving calls? I find that Voiceover calls this out all the time and it's very distracting. I just wish that there could be a way to send Voiceover speech, say, to Airpods, whilst keeping the main call on the Iphone speaker. Any thoughts? Many thanks.
