Hello, may I ask how to use this code you've written? I am trying to archive a list of twitch channels and the only thing I don't have right now are their emotes. I haven't figured out how to run this successfully, can you provide me more context please? I would greatly appreciate it! I have the channel names in a txt file currently separate by a new line and I can fetch the channel IDs using Twitch's API if needed. Thank you!

You need to go to twitchemotes.com and find the URL for their channel and pass that to the download_channel function

download_channel('https://twitchemotes.com/channels/40972890')
