Expected Behavior

There should be a way for apps to receive the activation-token from the global shortcuts portal.

Current Behavior

The Global shortcuts portal added in #711 is yet another way to launch apps.

When launching apps in wayland an xdg-activation token needs to be explicitly set to be able to bring the app window to the foreground.

But there is no support for passing the activation token in the Activated signal for global shortcuts similar to the ActionInvoked signal in the notifications portal.

So invoking an already running app using global shortcuts may not bring its window forward.

The global shortcuts system can't be used to spawn applications, only to send signals to them, but I do see the value of handing over an activation token. Should be possible to add that to the options vardict in the Activated/Deactivated signals.
