MS Teams and Exchange 2016 (Hybrid) calendar integration

Hi,

We have setup Exchange hybrid (Classic full) with Exchange 2016. All mailboxes are currently hosted on-premises on Exchange 2016. AAD connect is setup to sync users.

I noticed that new HCW doesn't configure federation anymore. I am looking to understand the requirements to have Microsoft Teams calendar working for on-prem mailbox users. Please advise on the requirements to achieve it and point me to any articles that can assist in setting this up.

Thanks
