Bots

Good day, tell me what this button is, what it is called, I can’t find information on what to do with it, it calls up the menu, but the bot does not respond to the category selection, when the / start menu is called, it’s working. How to activate this button?

This is a bot problem, not an interface problem. It's called ReplyKeyboardMarkup
