I am trying to use a Graph API call in a Flow that will assign a license when a new user is created. I am trying to build out the license assignment, and I am getting the error "error": { "code": "Request_BadRequest", "message": "Specified HTTP method is not allowed for the request target.",

I am not sure what is incorrect. The application I have being used had ReadWrite.All permissions for both Directory and Users. Here is the full JSON output and input.

Any ideas?

Input:

{
    "uri": "https://graph.microsoft.com/v1.0/users/67a9cbf3-d55b-47b3-b0d2-be1ba01f683d/assignedLicenses",

        "clientId": "Secret ID",
        "secret": "*sanitized*",
        "type": "ActiveDirectoryOAuth"
    },
    "body": {
        "addLicenses": [
            {
                "disabledPlans": [],
                "skuId": "f30db892-07e9-47e9-837c-80727f46fd3d"
            },
            {
                "disabledPlans": [],
                "skuId": ""
            }
        ],
        "removeLicenses": []
    }
}

Output:

            }
        }
    }
}

I expect and license to be assigned to the user, but I am getting a Request_BadRequest error
