how do you embed things like Ko-fi and YouTube videos? every time i try i get an error say "This service is not supported or the link is malformed". the code works correctly when i test it in a live HTML tester, and both Ko-fi and YouTube are on the 'supported services' list, so i don't know what the issue is. i've seen other people with the Ko-fi embeds on their profile, but it's not working for me and i've looked around for help to no avail. i don't expect an answer but it's been frustrating me trying to make this work
