Azure EventGrid Partner Topic Managed Identity access
I am trying to create a subscription for my partner topic in azure, I am pretty sure I am missing some sort of Auth shenanigans. Without auth it works, but i cant find any samples of how to do this with managed identity. The error message also incorrectly states that the ressource does not exist, even though the error is an access error.
Full Error:
