Any way to export a WiFi "Profile"?

I have an old Mac. In System Preferences (macOS Monterey), I have a "Profiles" option. That shows one entry: "XFINITY WiFi" I think this is from when I used to have an Xfinity account, because it automatically connects me to any Xfinity Wi-Fi networks - pretty nifty...except this isn't my main computer (and I don't have an Xfinity account anymore but the profile still works). I'd love to export this profile to my other main Mac but I'm not sure where it's stored or how to export it. Keychain Access? Somewhere else? Any help is appreciated.
