How to edit or unsend an iMessage | Apple Support

Starting in iOS 16, you can edit or unsend an iMessage after it’s been sent. To edit, touch and hold the message, tap “Edit,” make your changes, and tap the check mark to save. You have 15 minutes to edit the message up to five times. Both you and the recipient can view the edit history if using iOS 16. To unsend a message, touch and hold it, then tap “Undo Send” within two minutes, making it disappear for both parties. For more tips, subscribe to the Apple Support YouTube channel.
