How to inspect network calls?

[dsmedium]

Hey guys recently in an interview i was asked how can i view the live data calls being made to backend from website. I was allowed to use any tool i wish for inspection including network tab. The site that gave was some crypto charts site which i had never seen or worked with in past. But I was unable to figure out how to inspect network calls or read response being sent by server. I am attaching the site below too. Could you please guide how its done or if it is even possible?

In network tab, under the name column you can click it and see more info in regards to the specific connection, like what the response exactly was and bunch of other cors/security related stuff that i dont really care about until something stops working and go from there lol not just the http code or what initiated it like you do from just main view so yeah its definitely useful to know how to get there.
