MakeIAMPolicyConnection(Options)\n\nA factory function to construct an object of type [`IAMPolicyConnection`](/cpp/docs/reference/iam/2.34.0/classgoogle_1_1cloud_1_1iam__v1_1_1IAMPolicyConnection). \nThe returned connection object should not be used directly; instead it should be passed as an argument to the constructor of [IAMPolicyClient](/cpp/docs/reference/iam/2.34.0/classgoogle_1_1cloud_1_1iam__v1_1_1IAMPolicyClient).\n\nThe optional `options` argument may be used to configure aspects of the returned
