I’ve been searching for days for a way to do this. I’ve tried all combinations of sending keys through RIDE, Javascript, Python. Then I figured it out and it’s so simple it’s stupid. See below. And then just get source and send it to a json or text file. This probably works on all Chrome extensions that have a javascript to execute it. Hopefully this will help other newbies like myself. Using Linux btw.
Command in Robot:
Execute Javascript | /home/yourname/.conf/google-chrome/Default/Extensions/blahblahblah/3.0.4_0/wave.min.js
