how to watch firebase traffic from desktop chrome inspector

Question

I have a JavaScript app running in my desktop Chrome browser which is reading and writing to Firebase. I'd like to get a sense of how much traffic it uses (vs any local caching) and I figured I could just watch in the Chrome Inspector.

I'm not seeing any such traffic. I assume I need to tweak some Inspector setting, but it looks like I have everything turned on and nothing filtered.

How can I see this traffic? (For my current simple needs, I'd much rather do so in Chrome, and not have to fire up WireShark)

Firebase uses a websocket to communicate with clients. In the devtool's networking tab, filter by "WS" (websocket) and you should see the connection that Firebase is using.
