I am making a sales funnel of 3 videos in a chatbot and I want the client not to leave the chatbot in Telegram.

My video weighs from 150 to 400 megabytes, and Many Chat has a video size limit of 25 megabytes.

And as a result, I tried the speaker function, but, unfortunately, I could not set it up.

And now I would like to understand how to set it up, considering that I am not a programmer. Tell me how to do this as simply as possible and is it possible in principle?
