Nextcloud Online Office connection with AZURE AD Office

I am wondering if there is any setup guide how to connect the Nextcloud Online Office integration with the Azure tenant. This would make a big difference for the team. As for now we are using Nextcloud Office, but still there are some lags (also with High performance backend server) and some missing features. As the Office from Microsoft is the most popular we would like to connect our Nextcloud with the Microsoft 365 Office.

Has anyone dealed with this?
