You’re right Amigo. I had actually had this problem a while ago and had forgotten. So, back then, I found the extension in one of my old projects and have been using that.
I’ve tracked down the original github issue Choose Random Number or String given a string of values · Issue #209 · GDevelopApp/GDevelop-extensions · GitHub and here is the download link from that. I have checked it and it works.
