How can I utilize Creative Operation-Photoshop Action to automatically add pictures/icons to images upon upload in AEM Assets？

I've recorded a Photoshop action which involves placing a picture layer over the background image. However, upon exporting the Photoshop action file (.atn), I find that the file size is unusually small and doesn't encompass the image resources I added during the action sequence. Furthermore, while utilizing the Assets Tools via Processing Profile > Creative Operation > Apply Photoshop Action, I couldn't identify an option to upload the resources utilized within the action. Hence, I'm curious if there's a method to incorporate the images used in the action or an alternative approach to apply icons/watermarks to images online within AEM Assets?
