Remove "Chrome Apps" From Xubuntu Menu

Earlier today I installed Google Chrome only to realize that I needed to uninstall it for reasons I won't get into here, so I removed Google Chrome and got Mozilla Firefox back. Before I uninstalled Google Chrome, I downloaded an app from the Chrome Web Store that runs in its own window (not in Google Chrome) that added Chrome Apps into my Xubuntu menu so I can access it. I restarted my computer after the uninstallation, but the Chrome Apps submenu is still in my Xfce menu! I thought this was a problem with a file Google Chrome left behind, so I reinstalled Google Chrome just so I could type sudo apt-get purge google-chrome-stable, which should have deleted some of its files, but that didn't help at all but Google Chrome was still removed from my system like I wanted, including the Chrome App I downloaded. The links in the Chrome Apps menu are broken (like they should be because Google Chrome and the Chrome Apps were removed), but the folder is still there. How do I remove the Chrome Apps menu (or submenu or folder or whatever you call it) from the Xfce menu? Below is a screenshot of this problem.

Chrome installs app shortcuts to $HOME/.local/share/applications. You should be able to delete all residual launcher entries with the following command:

rm $HOME/.local/share/applications/chrome-*.desktop
