      org.freedesktop.portal.RemoteDesktop:
      @short_description: Remote desktop portal

      The Remote desktop portal allows to create remote desktop sessions.

      This documentation describes version 1 of this interface.

        Create a remote desktop session.

        A remote desktop session is used to allow remote controlling a desktop
        session.

        A remote desktop session may only be started and stopped with this interface,
        but you can use the #org.freedesktop.portal.Session object created with this
        method together with certain methods on the #org.freedesktop.portal.ScreenCast
        interface. Specifically, you can call
        org.freedesktop.portal.ScreenCast.SelectSources() to also get screen content,
        and org.freedesktop.portal.ScreenCast.OpenPipewireRemote() to acquire a file
        descriptor for a PipeWire remote. See #org.freedesktop.portal.ScreenCast for
        more information on how to use those methods.

        Supported keys in the @options vardict include:
        <variablelist>
          <varlistentry>
            <term>handle_token s</term>
