How to delete a chat queue?

I was trying to create a web chat for the console (https://trailhead.salesforce.com/content/learn/projects/set-up-the-service-console/set-up-web-chats-for-your-console?trailmix_creator_id=strailhead&trailmix_slug=prepare-for-your-salesforce-administrator-credential) however when I was creating a chat queue i entered the wrong date (i am EU and the date was supposed to be entered as USA mm/dd/yy) so it did not generate the chat code. Now how can I delete this chat queue and create it again from the beginning? i checked everywhere even under queues but i cannot find the one I created? I cannot finish the module because it does not generate/create the agent without the chat code!! Are you able to help?? Thanks!!!
