Connecting Calendar

I was having this problem repeatedly. I finally chose the option within Google to "Select All." I didn't want to do this, but that was the final solution to the problem. I do see this as something Zoom should not require. I don't want Zoom to be able to delete my calendars! I don't want Zoom to have all of that access! But that's what finally fixed the issue.

I also have no idea how to link my calendar to Zoom. And there is no help available. The instructions lead to constant issues that Zoom cannot access my Microsoft account and no solutions or help offered. Without a calendar to record the appoints that I make, Zoom is virtually useless to me. Tell me it is not so and help me find a live person to assist. How do I find anyone or anyhow to get live help?
