[How to uninstall an installed application?]

After creating Alist and modifying the custom domain name, it becomes completely unusable. How can I uninstall Alist and reinstall it? After reinstalling one, two Alists appear erroneously and both are being charged. The problem is that both of the two Alists I created are completely unusable, and on the page, there is only access and no one-click uninstall and deletion.
