Is it possible to get a list of contacts through Viber api?

Question

Viber

There, in the documentation, everything is tied to a public account, that is, you can get subscribers, for example, but is it possible to do the same only with a list of contacts? without a public account?
I did not find such an opportunity in the api documentation
https://developers.viber.com/docs/api/rest-bot-api/ - in short
