kentico xperience staging

Hi. Our company wants to migrate from kentico 11 to xperience by kentico. I plan to organize such an architecture develop->staging-> production. https://docs.kentico.com/documentation/developers-and-admins/configuration/content-sync-configuration using the documentation I figured out how to set up a develop and prod server. Tell me how to correctly set up an intermediate staging server to receive data from develop and send it to prod?
