Can't remove recurring meeting

I have a recurring meeting that I think someone invited me to from a couple of years ago.  Every week I get a notification on my phone that the meeting is starting.  I can't delete this meeting and I don't know who invited me.  Its not on my calendar (which is correctly connected to my google calendar).  Strangely, I also don't see it when logged into the WebUI or the Mac zoom app.  Only iOS.
