Open Modal from Board Menu Item Feature?

@dipro @andrest05 It would be great if the board menu item feature could be just a button click which sends a message to a background script app feature – requested here:

That would mean that the user would trigger the button press, and then the background script would listen for the message and take care of everything else.

The background script could do external calls, then open a modal or display a success/fail message.

It would also have details of the context from the item or items.
