Managing licence keys

I am currently using CleanTalk services for several websites, including one for a client. While I plan to provide the client with a full admin login to the WordPress dashboard, I have a concern about the visibility of the CleanTalk license key and email address within the dashboard.

Is there a recommended way to hide or secure the CleanTalk license key and email address while still providing them with full admin access to the WordPress dashboard? I want to ensure the security of the license key information.

Any guidance or solutions you can provide would be greatly appreciated. Thank you for your assistance.

Thanks
