We have a scenario where users from tenant1 are asking for approval guest users from tenant2.
The flow works up to a point where tenant2 user receives an email with the options to approve and reject.
The tenant2 user clicks on SUBMIT and receives an error "The remote endpoint returned an error (HTTP Forbidden). Please try again later."
Nothing shows up in the Flow logs on Tenant1 or during the flow testing.
What endpoint is being called in this scenario and what permissions should we assign to tenant2 users on tenant1 resources?
