      summary: Query if a room alias should exist on the application service.
      description: |-
        This endpoint is invoked by the homeserver on an application service to query
        the existence of a given room alias. The homeserver will only query room
        aliases inside the application service's ``aliases`` namespace. The
        homeserver will send this request when it receives a request to join a
        room alias within the application service's namespace.

            The application service indicates that this room alias exists. The
            application service MUST have created a room and associated it with
            the queried room alias using the client-server API. Additional
            information about the room such as its name and topic can be set
            before responding.
