calendar integration

[keg]

Until today, when I created a zoom meeting on my Mac, I was asked if I wanted to send it to my calendar and it went happily into my apple calendar. This evening (after losing and retrieving all my meetings altogether!) if I schedule a meeting, someone else's calendar which I share via microsoft 365, comes open and the only option is whether I want to put my zoom meeting in there! Why would I want to do that?! How can I get back the ability to enter my zoom meetings into my apple calendar?
