How to use Chrome-based actions in standalone Chrome "app"?

In Chrome it's possible to take a webpage and create a standalone "app".

However my various KM Chrome actions (Execute JS in Chrome is the main one I'm using) do not seem to be working in these standalones. Any thoughts on how to get this to work, or if it's possible?

I also tried Execute JavaScript in Front Browser and that didn't seem to work.

Bumping this to the top of the list... any help would be greatly appreciated! Even to know if it's not possible.

Have you tried following the manual's instructions to "Add additional Browsers to Front Browser Actions...", adding the bundle IDs of each of your web apps, then using the "Front Browser" tokens when your app is frontmost?

Go to manual:Single Page Version [Keyboard Maestro Wiki] and scroll down a few screens, or open the page then search for "Add additional Browsers".

I have no idea if this will work... Please report back!

Thanks so much for the pointer. I'll look into that.
