I need help how can I put the !POP option on it and I can only put the person online. How can I add joining, queued and sleeping?

You can use other placeholders from PlaceholderAPI, such as {server.players.queued} {server.players.loading} {server.players.sleepers}

But how do I use this in SmartChatBot

Please don't respond to old posts and create a new one. You literally use it as shown in your response text with placeholder API installed.

But I have no idea what exactly I should do?
Add these lines to the SmartChatBot cs file?

Hi,

Group Limits doesn't work on Carbon. No matter what you choose, only one player can be on the tc when you have Group Limits enabled, even if you set it to allow more.
