Is there a best practice or surefire way to verify that an RSC payload is actually streamed, ideally on the client?

In the past I’ve simply looked at the network timing, but is there something more concrete like a header I can check? Additionally, are there any tools for inspecting the payload as it streams in? The only one I know of is a community RSC Devtools Chrome extension, which works but is pretty cumbersome to use.

I have a load balancer that sits in front of my app, and in the past I’ve had to specifically configure it to enable streaming from the origin Next server. I’d love to be able to test that the ‘_rsc’ payloads are getting streamed appropriately from that.
