[Resolved] I have purchased "gp premium" and it does not appear on my desktop

I have purchased “generatepress pro” and it does not appear on my desktop. It says: you have not bought any downloads !!!

The purchase email (Dec-24-2107) says:

Dear Noriaki,

Thank you for your purchase!

Your payment ID is: 456257

First thing to note is that GP Premium is a plugin, not a theme. Many people try installing GP Premium as a theme and receive an error.

Instead, install it as a plugin and you’ll be good to go.
