While fiddling with the GitHub VSC plugin I accidentally made a test GitHub pull request to one of your challenge templates. Please is there any chance you can delete it?
I also opened a GitHub request (in progress) but I though I asked you too in case there are timeouts for these kind of things.
There is no way to delete the GitHub pull request, however,
you can close them by clicking the pull requests and then
look for the close option that is located below the comment
box. Click on I to close GitHub pull request.
