I am new to Make and not sure where to start to acheive this work flow or even if it is possible. Any suggestions will be great!

I envision a Telegram bot that acts as a speaking tutor in my educational Telegram channel. The student speaks in their language to the Telegram bot and it uses Google T2S and S2T and Google translate to interact by voice and text with the student to point the student to deeplinks in the channel for further practice. The questions from the student will be passed to the GPT app along with a pdf that contains detailed information about the education channel so that the responses will tutor or lead the student to the next things to practice in the channel.

I guess i just dont understand how the initial trigger will occur.
