Target platform — specifies the messenger in which this component runs. This is necessary if 2 or more messengers are connected, and some of the components should not or cannot be displayed in one or more of them.
For example, the bot is connected to all platforms. Buttons for Viber 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 Buttons under Buttons for Viber, where we specify Facebook Messenger, Telegram and Instagram in the target audience. Thus, one screen will look different for Viber and other messengers.
