Custom Worker Script on a domain basis no longer available in new dashboard?

For Workes & Pages, what is the name of the domain?

What is the issue or error you’re encountering

There is no longer an option to generate a custom worker script or edit code on a new worker template (my intention is to use it for geo-IP-based routing which I’ve used before on other domains). It appears there is only an edit code option available on previously created worker scripts, but no longer the option to create one outside of the existing templates?

What steps have you taken to resolve the issue?

I’ve looked through all Cloudflare documentation (to find that the interface has changed and instructions outdated). I’ve taken a look through the Worker interface and the template options available.

What are the steps to reproduce the issue?

  1. Go to Workers
  2. Create worker
  3. Try to edit/customise the worker
