Why do /delegatedAdminRelationships and /delegatedAdminCustomers requests always return an empty result?

Question

https://graph.microsoft.com/v1.0/tenantRelationships/delegatedAdminRelationships and https://graph.microsoft.com/v1.0/tenantRelationships/delegatedAdminCustomers  always give empty results, even when some delegated privileges are configured in the tenant.

Is this a bug in the API?

Response example:

{     "@odata.context": "https://graph.microsoft.com/beta/$metadata#tenantRelationships/delegatedAdminRelationships",     "@microsoft.graph.tips": "Use $select to choose only the properties your app needs, as this can lead to performance improvements. For example: GET tenantRelationships/delegatedAdminRelationships?$select=accessDetails,activatedDateTime",     "value": [] }

Hello Sylvain Rousselle,

Thank you for reaching out to Microsoft Support!

Please check if you have delegatedAdminRelationship in Azure AD Delegeted admin partners.

If you did not Create the relationship, returning an empty result is the expected behavior, and you can create it using the Create endpoint and then List it.

Hope this helps.
