Is it no longer possible to access dialogs and messages through the usual API for users?

Question

API

Getting a token...

https://oauth.vk.com/authorize?client_id=ххххххх&display=page&redirect_uri=https://oauth.vk.com/blank.html&scope=friends,messages,status,wall,offline&response_type=token&v=5.80

We are trying to get dialogues and nothing comes out here ...

https://api.vk.com/method/messages.getConversations?v=5.80&extended=1&access_token=...&count=10

Now only groups have access to dialogs and messages? If not, how to solve the problem?
