Absent 'Connectivity services'

I try to setup push notifications, so I created token on Rocket.Chat cloud (https://cloud.rocket.chat) and now have to input ‘Registration Token’ in ‘Administration → Connectivity Services’, but such chapter is absent:

Please, advise me how to get access to ‘Connectivity Services’ chapter.

I’m having this problem as well. There is no place to input the cloud token. Without this, notifications do not work. Anyone find the connectivity services tab or where to input the token?
