How to make a bot for VK conversation on Markov-Chain?

Question

In contact with

turnip github - https://github.com/kesha1225/NeuronBot
I have a VK bot script that remembers words from a conversation, then sends its already generated phrases and sentences (example: https://vk.com/vitalik1338 (not advertising ))
In the open spaces of Vkontakte, I saw bots that work the same way on Markov chains, but only send photos, like neurodemotivators (example: https://vk.com/neurodemotivators (not advertising)), there is also the "Sglypa" bot, which generates both text and polls and demotivators at the same time, etc.
I would like to make my bot generate text and demotivators at the same time, it will make demotivators from words and pictures taken from conversations.
Who knows how can I do this? For a month now I have been trying to find some kind of script or guide on how to do this, it still doesn’t work, and I’m not very good at python.
