By default sticky message widget area is coming on home page only. Some users are wanting it on all pages. I spent some times and got it. Now I am sharing the step-by-step procedure here and my members can easily implement it on their sites.
Open the front-page.php and remove this single line code from wellness_enqueue_front_script_styles() function.
wp_enqueue_script( 'wellness-front-script', get_stylesheet_directory_uri() . '/js/front-page.js', array( 'jquery' ), '1.0.0' );
