Workaround for missing API methods (get all layercomps)

[Karmalakas]

You could use getTemporaryFolder(), which IIRC doesn’t require user interaction. Same as getPluginFolder() and getDataFolder()

But beware, that running scripts from UXP might stop working on any time, even through actions (I think)

Can i run javascript.jsx file using UXP button

Do not do this if you plan on distributing your plugin to others. There is no guarantee that plugins that run JSX like this will continue to work in the future, and your plugin may be removed from the marketplace. Convert to batchPlay and the PS DOM API instead.
