Is it possible to give a link to customers to subscribe to the company's channel in Viber/Whats App?

Hi all. I know that in Telegram you can create your own channel and give a link to it to your customers so that they can subscribe. How is the situation with Viber / Whats App? For example, stores themselves begin to send advertisements to me. But can we give people links so that they subscribe to us, as is the case with telegrams?
And how do you create and confirm (green checkmark) the company's channels in vibers, whats app, telegram?
