So SSE has limitation of 6 simultaneous connections over HTTP1.1 and which can be overcome by using HTTP2 they say. Now what I'm not able to figure out is, how do I implement this in HTTP2?

In JS we just create EventSource object which subscribes to a endpoint and then we create listeners for different EventTypes server sends. From backbend (using springboot server with HTTP2 enabled, h2c) when I send a push notification, it always comes as HTTP1.1. I can't figure out what I'm doing wrong.

I've tested my server using curl --http2 that gives me HTTP2 protocol response so the backend is capable but not sure how to do that with JS EventSource.
