Trying to sing to Microsoft 365 Calendar from Drift

Question

I'm trying to connect my Drift account with my Miscrosoft 365 Calendar. Upon singing in from within Drift - after I enter my email and password - I get the following error message:

AADSTS700016: Application with identifier 'undefined' was not found in the directory 'ceolawcanada.com'. This can happen if the application has not been installed by the administrator of the tenant or consented to by any user in the tenant. You may have sent your authentication request to the wrong tenant.

Please help figure out how to resolve this issue.

Thanks.
