I make a workout app for Apple Watch and have just implemented App Intents for StartWorkout, PauseWorkout and ResumeWorkout using the Action Button on Apple Watch Ultra.
I want to add a secondary action that should be triggered when the Action Button is pressed a second time, but I can't find any documentation about how to accomplish this.
I have tried to just create another AppIntent, but it doesn't show up as an option in the settings app.
Any help with this would be much appreciated!
Documentation for this is in the works and should be published shortly. In the meantime, what you want to do is donate another AppIntent after the workout session starts. Secondary actions do not show up in Settings; they only make sense in the context of the current session, and you could theoretically donate a different "next" action based on user interaction or events that occur during the workout.
