Up Arrow to Edit Last Message on WA Web app

You can find the extension's source code on GitHub: https://github.com/valentincostam/up-arrow-edit-last-message

I get "You can only edit messages sent in the last 15 minutes"

The most useful whatsapp extension you will ever see, hug. Out of jokes, it would be awesome that you could recognize previous message to edit from the one you are in and edit previous one if you want, is the web whatsapp code very unconfortable to do that? How can I join the extension environment to try to learn to do things like that?

Works as expected. Thank you for the quality of life improvement
