MacOS URI Scheme for calling in MS Teams

I am looking for the URI Scheme that allows my macOS app to dial a number within MS Teams.

By calling tel:+14258828080 with urlForApplication on macOS uses facetime or the default app for calling.

How can we launch MS Teams from a 3rd party app? What's the URI scheme? For example, calling msteams:// will open the MS Teams app, but what are the parameters for triggering a call to be placed?

I also tried with the param msteams:/l/call/0/0?users=4:+14515422770. But this one leads to opening the MS Teams but not triggering the call.
