I am developing a telegram bot using python, and there is one thing I don't know if possible.
When someone sends in the channel a message, that is a reply to another message, and I receive it, can I see the first message, for which the reply is?
Sorry for bad English.
It's available as Message.reply_to_message, in your case probably update.channel_post.reply_to_message (in case you use python-telegram-bot, which you tagged)
