Support for bots to show dialogs.
For example, confirmation dialogs (1) and input dialogs(2):
Imagine a tik tak toe bot that wants to ask you a confirmation when you press the grid button. You don’t want to change the keyboard to ask confirmation or send another button.
Imagine a bot having a pagination and in the middle a button to go to the desired page. It’s not that good, after the user presses the button to send another message to ask the page. Because then the user replies and the message having the pagination goes 2 messages behind the chat.
I attach 2 screenshots showing the use-case of (1) and (2) for a UX improvement.
