MacBook Air M2 stuck in "recovery mode".

Hello, My niece has a MacBook Air M2 with a broken screen or screen connection. With no image on the screen, she activated recovery mode. Now it is possible to get an image every now and then by turning the angle of the screen/hinge slightly. By clicking on the apple (top left of the screen) and choosing restart, I hoped to be able to continue. Unfortunately, the device keeps restarting in recovery mode. Anyone have any ideas on how to get out of recovery mode? I want to connect an external screen so that we can secure important data on a external drive? Unfortunately, she doesn't have a backup of this data :'( . We have already connected an external screen. This works, but it is not seen as the main screen, which means we are still dependent on the screen, which goes out every few seconds and is difficult to get back on. I only have Windows devices and no knowledge of MacOs.
