It would be more future-proof to make this a structured message type. Something
like:

{type:'thirdPartyAuthToken', url:window.local.href}

Or it might be cleaner to parse it here--I don't have a strong opinion on that.

The sendMessage parameter is string typed. passing the redirectURL as the
message allows us to maintain the same interface as launchWebAuthFlow (that
calls its callback with the redirectURL when done).

+  window.close();
+}
