feature request: trigger an SSE start with the hx-trigger

Hello,

I found in the documentation that it is possible to trigger http callbacks on a specific sse event.
But I do not find anything (and don't seem to be able to get it to work) about using the hx-trigger tag to start sse requests on a user event (like a click to start the server sent events).

forgive me if I missed something in the documentation, but it isn't clear to me why in all my tests, my sse event are just triggered out of the box on page load.

Thank a lot for your help all.
