You're right @Anke

I'm changing and adding some functions, I hope some of that can be of help, I didn't find a way to select part of a text and use it in some functions that I need, that's why I decided to make this extension

The idea is if I scan an image, for example a debit card, it gives me all the text that that card has, but I only have to select the number and copy it to the clipboard, I just simplified that function, maybe later I will upload the update.
