Text quest on Corona SDK?

Question

Corona SDK

Hello everyone, I want to start developing my own quest on the corona sdk, at the same time I'm trying to understand Lua, the question is how to make the animation of the appearance of a message on the screen in the game, for example:
The player presses the button (to the left) and sees further the answer in the form of a message that pops up from below

Example message selection


I can create objects (message form), but I don't know what to do with them. Thanks in advance
