            session_entity_type (google.cloud.dialogflowcx_v3.types.SessionEntityType):
                Required. The session entity type to update. Format:
                ``projects/<Project ID>/locations/<Location ID>/agents/<Agent ID>/sessions/<Session ID>/entityTypes/<Entity Type ID>``
                or
                ``projects/<Project ID>/locations/<Location ID>/agents/<Agent ID>/environments/<Environment ID>/sessions/<Session ID>/entityTypes/<Entity Type ID>``.
                If ``Environment ID`` is not specified, we assume
                default 'draft' environment.

                This corresponds to the ``session_entity_type`` field
                on the ``request`` instance; if ``request`` is provided, this
                should not be set.
            update_mask (google.protobuf.field_mask_pb2.FieldMask):
                The mask to control which fields get
                updated.

                This corresponds to the ``update_mask`` field
                on the ``request`` instance; if ``request`` is provided, this
                should not be set.
            retry (google.api_core.retry.Retry): Designation of what errors, if any,
                should be retried.
            timeout (float): The timeout for this request.
            metadata (Sequence[Tuple[str, str]]): Strings which should be
                sent along with the request as metadata.

        Returns:
            google.cloud.dialogflowcx_v3.types.SessionEntityType:
                Session entity types are referred to as **User** entity types and are
                   entities that are built for an individual user such
                   as favorites, preferences, playlists, and so on.

                   You can redefine a session entity type at the session
                   level to extend or replace a [custom entity
                   type][google.cloud.dialogflow.cx.v3.EntityType] at
                   the user session level (we refer to the entity types
                   defined at the agent level as "custom entity types").

                   Note: session entity types apply to all queries,
                   regardless of the language.

                   For more information about entity types, see the
                   [Dialogflow
                   documentation](\ https://cloud.google.com/dialogflow/docs/entities-overview).
