How Do I add a custom button to the Social Buttons element?

Looking to add a TikTok icon button using the “Social Buttons” module but it is not allowing us to add this.

Below is the code we are trying:

// Register new icon as a theme icon
function avia_add_custom_icon($icons) {
$icons[‘tiktok’] = array( ‘font’ =>’fontello’, ‘icon’ => ‘e800’);
return $icons;
}
add_filter(‘avf_default_icons’,’avia_add_custom_icon’, 10, 1);

// Add new icon as an option for social icons
function avia_add_custom_social_icon($icons) {
$icons[‘TikTok’] = ‘tik-tok’;
return $icons;
}
add_filter(‘avf_social_icons_options’,’avia_add_custom_social_icon’, 10, 1);

add_filter(‘avia_social_share_link_arguments’, ‘avia_add_social_share_link_arguments’, 10, 1);
function avia_add_social_share_link_arguments($args){
$tiktok = array(‘tiktok’ => array(“encode”=>true, “encode_urls”=>false, “pattern” => https://www.tiktok.com/, ‘label’ => __(“Share on TikTok”,’avia_framework’)));
$args = array_merge($tiktok, $args);
return $args;
}
