Power BI Sign In URL - Connect via Browser

Hello World ... Of Experts !
After creating a PowerBI Entreprise App in the AAD to manager users and roles, we have to set up the Signin URLS in the "Entreprise Application"

So, please guys, does any of you know where we can finf the "Sign In URL", so we can finish our entreprise application setup in the AAD.
You can see in the PrtScr below the Tenant we need.

Very thanks & take Care

Joe
