Setting Authorization info for Webhook Endpoint Url

API Endpoint(s) and/or Zoom API Event(s)
Configuring the “Event notification endpoint URL” on the Event Subscriptions feature

Description
My test environment requires a specific Basic Auth header to be sent in the POST with the Zoom webhook; alternatively, it is possible to embed user/password information directly in the URL (again, this is a test environment, so there is no sensitive information / lower security).

There doesn’t seem to be a way to configure the Authorization header for the webhook POST; and it doesn’t seem possible to embed the user/password in the URL

Error?
On the Endpoint URL input, i get the error Wrong url format when I try to use an endpoint like https://user:pass@my.testenvironment.com/graphql/zoom … however, i’m able to use a URL like https://my.testenvironment.com/graphql/zoom (except my test server will not accept the POSTs, because of the lack of authorization info).

Which App Type (OAuth / Chatbot / JWT / Webhook)?
Server-to-Server OAuth
