How to purge all the cache for a worker.dev subdomain?

For example,
I have a worker deployed in https://polyfill.asvny.workers.dev/

The worker doesn’t request any origins because all the content is generated in the worker itself.
Because of bad logic, now my cache is corrupt with wrong values.

Now if I want to purge the whole cache, how to do it? I don’t think there is zone-id for a worker.dev URL

Note:

  1. I tried search for cloud API in Cloudflare API docs.
  2. I tried redeploying the worker.

Nothing worked
