[Решено] I can't find buttons to translate them

Background of the issue:
I am trying to translate buttons from the home page of скрытая ссылка. The buttons are: Read More, Learn More, Find Out Why You Should Visit Now. I am using Kadence Theme with Starter Template in Gutenberg and Classic Editor for posts and pages. I followed this page: https://wpml.org/documentation/getting-started-guide/string-translation/finding-strings-that-dont-appear-on-the-string-translation-page/#enable-auto-register-strings

Symptoms:
I can't seem to find the buttons in WPML String Translation. I enabled auto register strings and scanned the Theme and Plugins, but none of these buttons appeared.

Questions:
How can I find and translate the buttons: Read More, Learn More, Find Out Why You Should Visit Now?
