Parallels Toolbox subscription Expired message

I receive a daily message from Parallels stating that my subscription has expired and has an option to close or renew. I do not plan on renewing my subscription right now so I hit the close button but this message comes up every day. Am I required to update my subscription to use it? If not, how to I get this super annoying message to permanently go away?

 

You cannot use Parallels Toolbox without a subscription. You can uninstall it to avoid those alerts.
