Introduction
I have shared a few tutorials regarding Raspberry Pi and Telegram Bot before. But, since python 2 is no longer supported, I decided to make the latest tutorial using python 3. This tutorial will cover on library installation and sample program of Telegram Bot.
Video
This video shows how to control (Raspberry Pi GPIO) LEDs, buzzer and read buttons on Maker pHAT using Telegram app.
Hardware Preparation
This is the list of hardware used in the video.

Sample Program
This is python 3 sample program for controlling LEDs, buzzer and read buttons on Maker pHAT using Telegram app.

You can refer to the English subs.
I hope there is an English narrated version on the tutorial videos
