For example, the bot is connected to all platforms. Viber buttons are executed only in one messenger, and Viber is specified in the target platform by default. At the same time, for other messengers we need to add buttons that will not be executed in Viber. To do this, we add other buttons under Viber, where we specify Facebook Messenger, Telegram and Instagram in the target audience. Thus, one screen will look different for Viber and other messengers.
