custom social media icons

custom social media icons

Hello, good morning, I have tried to change the icons imported by Fontello, the icons appear but in the icons section when we add an icon but my icon does not appear in the social networks section, I already used the codes that come in the documentation. I have put them in the theme. child as in the parent theme and it marks an error I do not know what else to do I am using this code:

// Register new icon as a theme icon

function avia_add_custom_icon($icons) {
$icons[‘tiktok’] = array( ‘font’ =>’tiktok’, ‘icon’ => ‘ue801’);
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[‘Icon Label’] = ‘tiktok’;
return $icons;
}
add_filter(‘avf_social_icons_options’,’avia_add_custom_social_icon’, 10, 1);
