oauth for xojo plugin

Hi,

I am trying to run the sample from https://www.example-code.com/xojo/facebook_oauth2_access_token.asp

But I end up in this part of the code:

// At this point, your application should load the URL in a browser. // For example, // in C#: System.Diagnostics.Process.Start(url); // in Java: Desktop.getDesktop().browse(new URI(url)); // in VBScript: Set wsh=WScript.CreateObject("WScript.Shell") // wsh.Run url // The Facebook account owner would interactively accept or deny the authorization request.

Anybody can help me on what is the proper code for xojo this?

I hope somebody can help me
