Unable to target localhost with basic authentication

[airblade]

I have a Rails app running locally. It uses Action Mailbox which receives webhooks from mail systems such as Postmark. Action Mailbox requires incoming webhooks to use a URL with basic authentication like this:

https://actionmailbox:[email protected]/rails/action_mailbox/postmark/inbound_emails

When running locally, the URL needs to be:

http://actionmailbox:[email protected]:3000/rails/action_mailbox/postmark/inbound_emails

As far as I can tell the Hookdeck CLI does not support this. Please could you add it?
