Dynamics Sync redirect_uri

Hi team,

I am trying to integrate Dynamics CRM and Marketo, in the link  https://experienceleague.adobe.com/docs/marketo/using/product-docs/crm-sync/microsoft-dynamics/sync-setup/microsoft-dynamics-365-with-ropc-connection/step-3-of-4-set-up.html?lang=en

says that it is necessary to Register an application in Azure, the problem is that I need to know which value is required to add in the field   Redirect URL, because in the next steps it is necessary to use and in the documentation doesn’t say, Does someone know which information is set here?

Thanks

William
