How do I get the roblox avatar's face decal?

I've tried GetCharacterAppearanceAsync and GetCharacterAppearanceInfoAsync but none of them return the face decal

I've tried googling it but to no prevail as there hasn't been any threads over this, hence why I'm making this question

Is there any player-related function I can use to get the avatar's face decal? I've already looked over the player's functions but maybe I'm a blind dumbass

EDIT: I want to get the DEFAULT decal of the AVATAR'S face, since the decal is constantly changed.

There is a decal in character's head, usually called "Face" that contains the id of the faces.
