What is browser_broker.exe for?

Q. The stock Windows firewall (managed via Windows Firewall Control, WFC), blocked an internet connection attempt by this file. It appears to make the connection attempt when I open Edge and navigate to a webpage.

What exactly is it for? Why does it need an internet connection? Edge appears to be browsing fine without giving this file access to the internet.
