Ah, thanks @Jeff Arola – I don’t do any UXP development, so I don't have that active!
As the command is greyed out for "Insert Menu Command" and isn't recorded into an action, I don't know of a way to access this menu item via scripting.
I started doing some uxp programming and with this entry I convert actions to file. js, the problem is that whenever i have to convert the action i have to do multiple steps to select the item in the action menu, I need a script that calls quickly copy to JavaScript
