How to rename a worker subdomain?

How to rename a worker subdomain? I found that the worker subdomain is not replaced. help me.

Don’t think you can release and then re-register a new Workers.dev subdomain. Maybe you could try to contact support by sending an email to [email protected] explaining what you want to do and CF might be able to perform it.

If you do so, reply with the ticket number the confirmation email gives you.
