Is there a Bot that auto assigns after writing in specific channel?

Out of curiosity does anyone know if there is a bot that has an option to auto assign a role if someone writes in a specific channel?

The goal is to have a channel that will only be able to be seen if you type your in game account name in one channel which then allows you to see a hidden channel which we have a custom code to join community custom lobbies.

Obviously it would be able to be bypassed by someone entering in a fake account name or any spam message but we would simply remove their role or remove them from the server for providing fake info.

I know we could do a react bot but it wouldn't have the visibility of in game names to link to them when they joined our game.
