+
+        Args:
+            room_id: The ID of the room containing the parent event.
+            event_id: The ID of the parent event whose child events are to be returned.
+            rel_type: The relationship type to search for.
+            direction: The direction to return events from.
+            from_token: The token to start returning events from. This token can be obtained from a
+                ``next_batch`` token returned from a previous call or the `sync endpoint`_, or the
+                ``start`` token returned by the `messages endpoint`.
+                If omitted, results start at the most recent topological event.
+                When paginating, the ``from_token`` should be “after” the ``to_token`` in terms of
+                topological ordering, because it is only possible to paginate “backwards”.
+            to_token: The token to stop returning events at.
+            limit: The maximum number of events to return. Defaults to 5.
