Using a macro in the Sea of Thieves game, you can avoid being automatically thrown out of the game after 15 minutes of inactivity. For the macro to work correctly, you need to take the flashlight in your hands and activate it using a keyboard shortcut. This will allow you to stay in the game for a long time, without the risk of being kicked due to inactivity. It is important to remember about using a macro within the acceptable rules of the game.
