[💫 Feature Request ] Allow SSE to use POST /w payload

[XChikuX]

There is no technical reason to prevent SSE from sending a POST request or limiting the API to be payload-less

This issue is a very modest request to allow more advanced payloads for SSE.

I looked for existing implimentations and found This

I've already integrated it as an EventSource drop-in replacement to SSE and it works great.

Upon adding a payload (namely a captcha) and making it a POST request, everything works as expected and is very stable.

Would it be possible to integrate htmx 2.0 SSE extention with this solution?
