Using a custom icon in with Coder theme

Hi there,

I am trying to add a custom icon for TryHackMe with the Coder theme, but I havent had any success in doing it.

I ended up coming across a fairly similar question asked here, but unfortunately after following it, it doesnt work and I have a bunch of errors.

This is the format im trying to be use, (for icon = “”, its usually fa fa-2x fa-linkedin or similar, but because what i want is not available, i am looking for alternatives):

name = "TryHackMe"
icon = "/images/social/tryhackme.svg"
weight = 4
url = ""

I would really appreciate any help. Thank you.
