How to modify mobile nav menu text in theme

Question

I'm using a child theme based on Theme Nectar's Salient WordPress theme, and I'm encountering a frustrating issue in attempting to modify the text that displays for a sticky nav sub-menu in a collapsed (mobile) state. After digging through the parent theme files, I'm seeing that the php code responsible for the submenu, located in a "nectar-vc-addons" sub-folder, is as follows:

echo '<a href="#" class="mobile-menu-link"><i class="salient-page-submenu-icon"></i>'.__('Menu',NECTAR_THEME_NAME).'</a><ul  style="background-color:'.$bg_color.'; color: '.$link_color.';" >'.do_shortcode($content).'</ul>';

This results, in part, in the following markup being generated for the menu:

<a href="#" class="mobile-menu-link">
    <i class="salient-page-submenu-icon"></i>
    "Menu"
</a>

All I want to do is change this "Menu" text to something different, and there doesn't appear to be a theme option to do so; and I'd like to avoid altering the PHP in the theme file so it's not overwritten in the event of a theme version upgrade.

I realize I can use some jQuery trickery to alter the string, but I'm wondering if there's some way I can change the text in the functions.php file in my child theme or some other way? I'm open to CSS approaches as well perhaps using psuedo elements, but I can't come up with anything that works in changing the text within the anchor element and keeping the icon. Any assistance here is greatly appreciated!

You can leverage the use of the gettext filter to change the text. Add this code to your child theme's functions.php or to a plugin:

add_filter('gettext', 'wpse248225_change_text', 20, 3 );
function wpse248225_change_text( $translated_text, $untranslated_text, $domain ) {
    if ( NECTAR_THEME_NAME !== $domain ) {
        return $translated_text;        
    }

    // Make the changes to the text
    switch( $untranslated_text ) {
            // Change 'Menu' text
            case 'Menu':
                $translated_text = __( 'something different', 'text_domain' );
            break;

            // add more items
     }

    return $translated_text;        
}
