Remove a Website from CleanTalk

I have a wordpress website which has now been moved to WIX, but the website is still showing on my CleanTalk dashboard & I am assuming using one of my licences. I no longer have access to wp-admin for the site so I can’t simply remove the plugin. I do have access to cPanel so could delete the files if that is the solution.

How do I remove this website from my dashboard?

Thanks.
