How to Un-Mirror front facing camera.

Hi,

I want my front facing camera to be un-mirrored so that when I take a selfie, the picture is already flipped.

How do I do this? If this feature is not yet installed into iOS, please Apple add this feature into it. Because sometime I use my phone as a mirror and would like to see my face from the second person point of view.

Also, I own an iPhone X.

Thank you,
