How to view outgoing connections of an application in windows?

Question

Windows

Greetings.
Can you tell me a utility with a graphical interface in which you can see all established connections (ip-addresses, domain addresses, etc.) for a particular process and all other processes generated by it?
Something similar to the network activity analysis (Network) in the developer tools of the Google Chrome browser.
The situation is this: there is a harmless application in which cef (Chrome browser) is built in. After adding a certain plugin to this application, additional cef processes appear (apparently using api-applications, the plugin spawns new processes), which from time to time behave extremely suspiciously: they display js-alert notifications from casino sites. It is necessary to identify what happens in these processes, what connections and with what they establish.
