Feature Request: Support for HMAC Authentication in API Explorer

Hi ReadMe Team,

I was wondering if there are any plans to add support for HMAC authentication to the interactive API Explorer?

Many APIs, including ours, rely on HMAC for secure request signing. Without this capability, developers can't test these core endpoints using the explorer, which limits a key feature of the platform.

Please consider adding support for HMAC authentication to the interactive API Explorer.

This functionality is available on other documentation platforms (both Swagger UI and Redocly) and would be a critical addition for any customer whose API requires signed requests.

Thank you.
