How do we change the text "Search" in the search button?

I hope you are well today and thank you for your questions.

The search form and its placeholder text are displayed by the theme that you are using on your site so you can change it by editing theme searchform.php file in the child theme as described in the following page.

We are going to implement these options in the future version of the plugin so that you can change it easily.
