Apple

Was cleaning my 15 Pro Max today and never noticed this until o put straight light into the telescope camera when I was checking if everything was clean, right inside the lens a tilted horizontal line., at first looked like a scratch inside the lens , but looking with some attention under the light it was a very straight line, is not affecting the photos at all, just checking if this is normal on 15 Pro Max? to check this put the telescope lens right under a flashlight light or lamp light.
