How do I cancel a stuck app update in the app store in Mojave? | Mac

I’m trying to download the latest update of Xcode from the app store in Mojave. I started the download/install process after upgrading to Mojave. It’s been now over 3 days that the download/install is stuck. Although this happens every time there is an Xcode update, so I’m not surprised.

However, in earlier versions (Yosemite, El Cap, Sierra), to cancel a stuck update, I would normally go to the “updates” page, and use “option + click” to cancel an update. The “Purchases” page was another option to do the same thing. However, in Mojave, “option + click” no longer cancels an update (neither does just the click). There’s no “Purchases” page too in the new app store in Mojave.

Sometimes it’s “waiting”, other times it’s “installing”. And all this while, I haven’t been able to use Xcode at all.

How do I go about canceling the download?
