Change "Icon_name" after adding own social icons

This “icon_name” are only placeholder texts.

you had to change it to your needs f.e.

// Register new icon as a theme icon
function avia_add_tiktok_icon($icons) {
	$icons['tiktok'] = array( 'font' =>'entypo-fontello', 'icon' => 'ue8fa' , 'display_name' => 'TikTok');
	return $icons;
}
add_filter('avf_default_icons','avia_add_tiktok_icon', 10, 1);

// Add new icon as an option for social icons
function avia_add_tiktok_social_icon($icons) {
	$icons['TikTok'] = 'tiktok';
	return $icons;
}
add_filter('avf_social_icons_options','avia_add_tiktok_social_icon', 10, 1);

that display_name was new to me too. It is only necessary if you need a special writing for the icon (also for hovering). Here it is the second big T in the icon name ( like WhatsApp etc. )
