Activates the named application action.
You may only call this function on action names that were returned from list_actions.
Note that if the main entry of the desktop file indicates that the application supports startup notification, and
is non-null, then startup notification will be used when activating the action (and as such, invocation of the
action on the receiving side must signal the end of startup notification when it is completed). This is the expected behaviour of applications
declaring additional actions, as per the desktop file specification.
As with launch there is no way to detect failures that occur while using this function.
