Messenger chat heads are a great way to keep your conversations organized and easy to find. You can add them to any conversation by selecting the “Chat Heads” tab in the Messages app, and then clicking on the “Add” button. Once you’ve added a chat head, you can use it in any conversation by selecting it and pressing the “Talk” button. The chat head will appear in the bottom right corner of the screen, and you can use it to start or end conversations by pressing the “End” button. If you want to add a new chat head, just select it from the list and press the “Add” button again. You can also remove a chat head by selecting it and pressing the “Remove” button.
