Java2OP and dx tools

Hello,

I want to make this tutorial : http://docwiki.embarcadero.com/RADStudio/Rio/fr/Utilisation_d%27un_ensemble_personnalis%C3%A9_de_biblioth%C3%A8ques_Java_dans_vos_apps_Android_RAD_Studio

But I didn't find dx tools and i can't download Java2OP on edn. I have an RAD Studio 10.2 Tokyo Architect so normally I hope I have the rights to download those tools...

Anyone from Embarcadero can help me please ?

Thank you in advance
