How do I connect my app to chat?

I have a feeling that I might just have to use a real account dedicated for the bot. Thank you for all the help.

After doing this again, results:

Link:
http://localhost/?code={code}&scope=chat%3Aread+chat%3Aedit+channel_editor

Code (config):

const config = {
    options: {
        debug: true
    },
    connection: {
        cluster: "aws",
        reconnect: true
    },
    identity: {
        username: process.env.CLIENT_ID,
        password: "oauth:"+process.env.ACCESS_TOKEN
    },
    channels: [channel]
}

Output:
