Poll For Result Using Function Invocation Request

Deprecated and will be removed soon. Please use the new NVCF Invocation API endpoint to invoke a function and stream results without polling. Retrieves the status of an in-progress or pending request using its unique invocation request ID. If the result is available, it will be included in the response, marking the request as fulfilled. Conversely, if the result is not yet available, the request is deemed pending. Access to this endpoint mandates inclusion of a bearer token with 'invoke_function' scope in the HTTP Authorization header. In-progress responses are returned in order. If no in-progress response is received during polling you will receive the most recent in-progress response. Only the first 256 unread in-progress messages are kept.
