I am trying to use the 'Add member to Group' action in my flow. I have a 'Create Office 365 Group' action working fine and I have a 20 second delay built in. But when I pass the Group ID to the 'Add member to Group' action it returns a 404 Resource Not Found error. Here is the error...
"Resource 'c843d56d-a727-4c4d-bdb1-c03e4d097d15' does not exist or one of its queried reference-property objects are not present."
