Gmail keeps adding meeting invites to my Apple Calendar.

iPhone 15 running iOS 18 just urgraded to 26, iPad Pro iOS 18, 2025 Mac. I have a Gmail account that my husband uses to share his call schedule at the hospital. If the account is not "turned on" in the native Calendar app, the schedule won't show up. However, because I also use this same email account for some personal stuff, when I get a Zoom or Microsoft Teams invitation to this email address, the invitation is automatically being added to my Apple Calendar and I cannot get rid of it without responding to the invite. I have researched this exhaustively over the past weeks and cannot find any kind of setting to turn this off without changing the gmail address for the call schedule sharing. I am not sure if it is a gmail thing or an Apple thing (so I will be posting this question on other forums as well) or something that these particular meeting sites do. I have tried every setting change that I can find from other people with a similar issue. Some of the settings people have mentioned don't seem to still be available in iOS 18 and 26. What is interesting is that in my calendar the call schedule and the "regular" gmail are two separate options (not in iCloud - see below) and even if I have the regular gmail unchecked it is still happening. Does Microsoft Teams and/or Zoom invitations have the ability to send an invite to my Apple Calendar? Also, that gmail account is also the same as my Apple ID, so that doesn't help. Any thoughts?
