Cloudscript Workshop--Where is It?

I cannot find this thing. It’s really frustrating because I’d like to code some stuff and I’m too DERP to find this thing that’s probably clearly labeled. If someone could help, it’d be greatly, greatly appreciated.

I know how to open the Cloudscript panel, btw, so don’t say “HURR CLICK ON CLOUD BUTTON DERPDEDERP.” That’s obviously step one of ???.

I thought there was a way to get there inside the game itself…
