Messenger that will unite Viber, Watsapp and Telegramm in one window / application?

Question

Messengers

There is a need to combine all these 3 applications in one application, whether it be a program or a web application.
And it is very, very important that these 3 messengers are in the "single window".

Answer 1

Try multichat from Calibri https://clc.am/callibri1 where you can add any messengers and reply in 1 window.
Here are other similar services that will suit you:

Answer 2

Viber does not have a WEB version. You can only merge WhatsApp and Telegram.

Answer 3

I asked myself this question at my last job and used a good and simple All-in-one messenger app https://allinone.im/
where you can add tabs of many different messengers as much as you like (and everyone will be as a separate account)
