Hello CCT,
Thank you for reaching out to our technical support forum. I’m sorry to hear about the trouble you’re experiencing.
We will consider adding tiktok option there. Meanwhile, you can follow this trick. Find one social media that you will not use. For example, I have taken LinkedIn. Then I have added the Titktok url there. After that, I have used Custom CSS to change the LinkedIn icon to Tiktok. This is the CSS I have used.
.fa-linkedin-in:before{
content: '\e07b';
}
Here is a short screencast for you:
