Unfortunately, there is no option to add the Custom Social Media in the header in our theme, Our theme provides the functionality to add the new Social Media using the “Social header element” but you can only select from the pre-given options: https://postimg.cc/fJgX3bSd
If you want to set and choose your own Custom Social Icon then you can use the Custom HTML header element and then set the Custom ICON using the Custom HTML code in it, it will work for you: https://postimg.cc/RJ7sSHZw
Otherwise, this requires additional Customization and it is not included in the theme support policy, If you want paid Customization services submit a customization request to WPKraken team.
