Just a little snippet of php is all ya’ need!

/* Hamburger Menu */ 

add_filter( 'generate_svg_icon', function( $output, $icon ) {
    if ( 'menu-bars' === $icon ) {
        $svg = '<svg width="16" height="9" viewBox="0 0 16 9" fill="none" xmlns="http://www.w3.org/2000/svg">

</svg>';
        return sprintf(
            '<span class="gp-icon %1$s">
                %2$s
            </span>',
            $icon,
            $svg
        );
    }
    return $output;
}, 15, 2 );

If you want to put your own icon in there, you just need to replace everything in the <svg>...</svg> tags.

I used the fill of “currentColor” so you can continue to color the icon using the theme’s customizer settings — so if you swap your SVG out, make sure to replace any colors with “currentColor“
