title: Google Tasks error 403 : Error :disallowed_useragent android
body: <p>I am using Embarcadero RAD STUDIO 10.2 and would like to propose a Google authentification to connect on my Android application
  I have an error 403 : Error :disallowed_useragent 
  when I compile my application for android 
  but not when I compile for windows 
  Does anybody have had similar problem ? 
  I cannot find how to modify the user agent for a Webform on Delphi FMX (not VCL)
  Thank's a lot for your help :):)</p>
