Unable to give apps permission to use microphone

HI, I'm trying to use zoom on my ipad but I am muted in all meetings even my own. None of the settings in Zoom are muting me. Zoom keeps telling me to go to Settings>Privacy>Microphone and give Zoom permission to use the microphone. however when I do that the microphone settings do not show Zoom. It only says, "Applications that have requested access will appear here" but no apps are listed. Microphone works fine in Facetime on the Ipad. I've spent 2 hours reading zoom and apple forums about this and have done all of the following: updated software on ipad, reset privacy settings, uninstalled and reinstalled zoom 4 times, made sure no other apps are using the microphone, but none of that works.

I know this is an issue many people have had over the years because it's been asked repeatedly since 2014. I've tried all the solutions I can find in previous apple Forums but they are now fairly out of date. Can you help with this?
