How can I protect my MacBook Air screen from scratches and marks?

I purchased MacBook Air M1 2020 model in April 2024. And after a few weeks I started noting that there are imprints/ marks of the keyboard have started forming on the screen. I thought in the beginning that I should not use any screen protector and silicone keyboard. But disappointed with the key imprints forming on the screen I started using silicon keyboard. but that did not resolve my issue. should I put a screen protector on the screen and protect the screen from further imprints being caused. Because the imprints which have already been formed on my screen can't go away.

I should have used the screen protector from the beginning only. I wasn't aware that even an apple product can have such a design flaw that the keys of the keyboard are leaving a mark on the screen.
