Switch off the calendar feature totally

Zoom Business account - newest version of Zoom-App on Windows 10 - Integration of  Zoom in Outlook is not marked and I don't work with Outlook (it is even not installed on my Notebook)

Somehow Zoom always triggers the installation process of Outlook and this even pops up during Meetings (even though system notifications are not allowed). This all is really annoying.

What can I do to totally switch off the calendar feature (we don't work with it) in Zoom (even in the business account itself or at least in the local Zoom-App)? Didn't find a switch or anything! There are only the three possibilities of connecting calendars but no switch to turn the calendar function off.

Thanks for your hints, tipps and feedback.
