Can't Delete Recurring Meeting that shows up ONLY in stand-alone app, not on Web-based Home Page

Someone created a recurring meeting within Zoom last year and now I can't delete it from within the Mac app. All suggested solutions I've found online do not work. I don't get a "hover" option when I click on the recurring / upcoming meeting. I don't have any calendars synched that I'm aware of. I simply must have accepted this invite and the host hasn't deleted it. How to I clear it out of the app? Thanks.
