Message Replicator Telegram bot

I need to create a bot that replicates the messages from a normal account to a group and forwards the responses they give from that group to the original group, I mean, it serves as an intercom.

Example .. if I have two telegram accounts and there is an account that is in a group that the other is not. I can create a bot to put it in a group with my two accounts and that if I write a message in that group with the account that is not there, he will take care of forwarding that message through the account that is and copy the responses and forward them to the group with my two accounts
