Cosmo router is blocking the response when subscribing via SSE, until at least one message is received which causes a timeout

What happened?
When subscribing to a subscription via SSE, cosmo router is blocking the response until at least one message is received from the subgraph which can cause a timeout if no messages are received within 1 minute. (depending on the timeout).
Cosmo router should flush right away, with a text/event-stream Content-Type even if no messages are streamed, and maintain the connection until is closed by client

hello @endigma not sure if this issue is a duplicate, it can be solved using heartbeats but only if your client can handle them, which in my case it doesn't. I think the router should do an one time flush after the subscription is done , just to establish the connection with the client
