Count specific strings of on a channel's chat

[Foot_Balld]

I would like to know how I can read the chat of another channel to for a specific amount of time e.g. one minute to count specific string or emotion. I am trying to create a simple app w/ nodejs using tmi.js but the documentation shows for channel owner options (mod, etc…). Any help would be apperciated.

To join a channel with tmi.js you would use this

client.join(“channel”);
