OneDrive for Mac - Sharepoint 2019 (on premise)

Hi.

I just want to synchronize a Sharepoint Library with a Sharepoint 2019 server.

I've setup the App comming from Microsoft (not from Apple AppStore).

The application is able to see my personal site in Sharepoint, and synchronize. No problem.

When I use with Safari the Sharepoint Library, when I click on the Synchronize button, it shoud add a new URL in the OneDrive app (it's how it works in Windows). In that case, nothing happens. I've tried another web browser (Chrome), without success).

I've verified the behaviour with Macos 10.13 and 10.15.

Regards
