iPhone as Zoom Mico

[eedubya]

Several weeks ago during a music lesson I was trying to share my audio from my music software and my instructor couldn't hear it (I haven't had to share my screen or sound since then so I'm not sure if the issue remains). At the time I went through settings and tried choosing different settings and somehow I made my iPhone my default microphone. So everytime I log onto a meeting I get a noticed on my iPhone and have to disconnect it in order to use the mic on my computer. Yesterday I had my bluetooth on my phone turned off and spent 10 minutes trying to log onto a meeting before I realized what was going on (I turned my bluetooth on, restarted the meeting and disconnected my iPhone as the mic). I've tried going into settings to remove the iPhone from the list, but when I go there I don't see it as an options (screenshot attached). If anybody could help me with this issue I would greatly appreciate it.
