I am trying to create a button in gmail to run the following google apps script code:Google Apps Script Code
This code allows the extracting and backing up of images embedded in emails.
I have used the code and added it to a project in script.google.com and it currently works. I would now like to add it as a gmail addon so it can be executed whenever needed within gmail itself.
I have followed the guide here: Quickstart: Gmail Add-on, but it doesn't seem to be working for me.
The google apps script code and the gmail addons are new to me, but any help appreciated. Be gentle..
Thanks.
