Setting a custom app on tap action by the user

Hello, is there a way to set a custom or programmable button by the user?

What i mean is i want to have tap on action but when i tap it on my watch i want to set the program to open and not to be preset by the watch designer.

I found the custom app by id but i want to be able to set the app from my watch.

You need to use Double Tap. and for the action select Open App then select App Switgher.
The user then double taps and selects the app for the button. Then in subsequent uses if he taps the app the user selected is opened.

The feature app switcher shows among selectable apps only if interaction double tap is selected.
Then it can be found on the end of the list.

Nice thank you, was also looking for this. Got it working, much appreciated.
