php – Divi – add title to cell menu button

I am attempting so as to add title to the hyperlink to cell menu button in Divi theme. I do not wish to edit mum or dad theme, so I created little one theme and I attempt to lengthen class.

In capabilities.php I’ve:

operate divichild_includes() {
    require_once get_theme_file_path( 'consists of/class-divichild-menu.php' );
}
add_action( 'after_setup_theme', 'divichild_includes' );

and in class-divichild-menu.php:

class Divichild_Builder_Module_Menu extends ET_Builder_Module_Menu {

    public operate render( $attrs, $content material, $render_slug ) {

        $mobile_menu = sprintf(
            '<div class="et_mobile_nav_menu">
                <a href="#" class="mobile_nav closedpercent1$s" title="cell menu">
                    <span class="mobile_menu_bar"></span>
                </a>
            </div>',
            'upwards' === $submenu_direction ? ' et_pb_mobile_menu_upwards' : ''
        );
    }
}

new Divichild_Builder_Module_Menu();

I am getting deadly error “Class ET_Builder_Module_Menu not discovered”.

I attempted with prepending ET_Builder_Module_Menu with “/” and with completely different precedence of hook and it does not work.

I do know, I might add title with javascript, however I feel, that doing it in php is extra correct resolution.
