Hi
My name is Daniel. I am an Independent Advisor and consumer of Microsoft products, I will be more than happy to help you.
Unfortunately the MS Team free only comes with limited scheduling features or a non-fully functional calendar. You also can't see or sync the meeting invites from your email inbox to the MS Team free desktop app. If you need a fully functional scheduling feature then you need to purchase a paid plan.
Please see the demo video regarding the scheduling feature in Microsoft Teams Free:

As you can see on the demo video above On the MS Team free Desktop app you can see the meeting/calendar icon on the left menu, but when you click the schedule meeting button the MS Team free desktop app will open a new browser tab then redirect you to Outlook.com/Gmail web app. So actually you will schedule a meeting calendar on Outlook.com/Gmail web app and not on MS Team free app.
