Render Real Body in First Person Like a Resource Pack (Bedrock or General)

That can be useful to any modder that want to edit or animate the body and can see in first person, whether because wants to make seems more inmersive or something like this without having to turn the mod to Behavior Pack. I guess that this can't be used to trick the game honestly because you don't gonna move the camera and nothing like this. I can say that this meets the requirements to be added to resource packages.
