Menu item visible on mobile

i have a one page site with 1 menu item (phone number) i would like for it to be visible on mobile instead of the 3 bars menu. i tried altering code i found for secondary menu but i think i have the wrong hook

add_action( 'wp_enqueue_scripts', 'generate_dequeue_primary_nav_mobile', 999 );
function generate_dequeue_primary_nav_mobile() {
   wp_dequeue_style( 'generate-primary-nav-mobile' );
}
