Summary

Hello!

With the 2024.3.X onwards we are able to perform OAuth authentication with client credentials. With this feature request, we would like to have an input for additional query parameters in the request URL such as audience. This is an mandatory attribute in many of the authorization flows.

Why should this be worked on?

1. Developers are not able to use Client Credentials authentication due to missing audience
2. Enables more user to Hoppscotch as audience is highly use in many authorization servers.
