Allow anonymous user to access Themes Customizer

I created a theme and use Themes Customizer. Is there any way I can give anonymous users access to the themes customizer without the ability to save it?

It will be very convenient in terms of user experience if users are able to know what kind of theme customization we offer and how they can change it.

Thank you

Try using this solution to give access to users to a specific page without them having to register an account.
