Enabling Screen Lock Feature When Flipping iPhone Screen Down

Hi Community,

I'm frequently using my iPhone at my desk and thought how convenient it would be if I could lock my iPhone's screen by simply flipping it screen-side down. Similar to how the screen locks during phone calls when the phone is near the ear. But I couldn't find such a feature in the settings. Is this possible using Shortcuts, or maybe there is such a function deep in the settings somewhere?
