      30   * GRemoteActionGroup:
      31   *
      32   * The `GRemoteActionGroup` interface is implemented by [iface@Gio.ActionGroup]
      33   * instances that either transmit action invocations to other processes
      34   * or receive action invocations in the local process from other
      35   * processes.
      36   *
      37   * The interface has `_full` variants of the two
      38   * methods on [iface@Gio.ActionGroup] used to activate actions:
      39   * [method@Gio.ActionGroup.activate_action] and
      40   * [method@Gio.ActionGroup.change_action_state]. These variants allow a
      41   * ‘platform data’ [struct@GLib.Variant] to be specified: a dictionary providing
      42   * context for the action invocation (for example: timestamps, startup
      43   * notification IDs, etc).
      44   *
      45   * [class@Gio.DBusActionGroup] implements `GRemoteActionGroup`.  This provides a
      46   * mechanism to send platform data for action invocations over D-Bus.
      47   *
      48   * Additionally, [method@Gio.DBusConnection.export_action_group] will check if
      49   * the exported [iface@Gio.ActionGroup] implements `GRemoteActionGroup` and use
      50   * the `_full` variants of the calls if available.  This
      51   * provides a mechanism by which to receive platform data for action
      52   * invocations that arrive by way of D-Bus.
      53   *
