Multi-Tennant Authentication

**Is your feature request related to a problem? Please describe.**
Currently I only seem to be able to use one account to connect to Azure and we have other tenants with different accounts to access. [...]

**Describe the solution you'd like**
I'd like to be able to state I want insights using abc.com with one account and ext-abc.com with another account

**Describe alternatives you've considered**
I have no other options at this point since the account used to access the 2nd tenant is not an AD account and I cannot run PowerBi with that account to try and make a sperate connection into Azure.

**Additional context**
