github.com/hoppscotch/hoppscotch@e9e1366cc8/packages/hoppscotch-common/src/helpers/realtime/SSEConnection.ts (L46-L52)

hoppscotch uses addEventListener to capture SSE messages, but since https://sse.dev/test don't send the event field, it can't be caught by addEventListener

However, SSE connections without the event field are common; for example, ChatGPT SSE connection also lacks the event.

A method to capture unnamed events, that is, without the "event: <event_name>" field, would be nice.
