i'm trying to create a microsoft edge extension to save pdf edits automatically. Can i inject a script to a file uri scheme. ie, file:///example.pdf. (this is my browser screenshot). There is a save button on right-top of the screen.i want to autoclick that button when an edit occurs.but i need to inject a file to that tab. what code should i include in manifest file?
or any of the browser will support this feature?
