Cross tenancy connectivity via Function App

I have a Function App that connects to a secondary Tenant that sends alert data from Defender to Sentinel. The account that was used initially for the Function App has been deleted and I am looking to replace it. Can a Managed Identity be create din the second Tenant and then used by the Function App to receive the data and if so what permissions would the Managed Identity need to ensure the alert data triggered by Defender is received in Sentinel?

@Clark, Jason Thanks for reaching out.

Unfortunately you cannot use Managed Identity for different tenant resources.

The same is documented here.

No. Managed identities don't currently support cross-directory scenarios.

Let me know if you have any queries or concerns.
