MS Teams meetings not available in MacBook Pro calendar but in iPhone calendar

I am cooperating as a consultant with different customers and that means cooperating with help of Teams. I have MS 365 on my MacBook Pro but I am not using MS Exchange, I use Apple mail and Apple Calendar. When getting Teams invitations to my Exchange account the meeting is visible on my iPhone calendar but not on my MacBook Pro calendar, this even if both calendars have the exchange calendar. On my MacBook I need to use the Team app calendar to join and to manually add a teams meeting making the meeting visible in my MacBook calendar.

Any one who has a solution to my problem?
