Pusher Channels Docs | How to authenticate userspage

Hello there, I spotted an issue on https://pusher.com/docs/channels/server_api/authenticating-users/

According to the docs, I have to follow the following response code when making authentication handler.

∞ Response
Unsuccessful responses from an authentication endpoint should serve a 403 Forbidden HTTP status.
Successful responses from an authentication endpoint should carry a 200 OK HTTP status and a body of the form

However our backend follows HTTP code semantics.

• Unauthorized will be sent if the client does not specify the token in the header
• Forbidden will be sent if the client does not have access
• Internal Server Error will be sent if there is unexpected error that can't be handled

The documentation saying it only accepts 403 is very limiting. I wonder if the wording is "should" because it'll accept other 4xx error and 5xx error. Please let me know.

Start with the Pusher Channels authenticating-users documentation and its Response section. Verify how authentication endpoints handle unauthorized, forbidden, and unexpected-error responses, then clarify the documented status-code requirements and explain what successful completion should say about accepted error responses.
