Make StarterCharacter load Player's appearance

I am working on a custom R6 StarterCharacter but I still want it to load each player’s appearance (shirt, clothes, accessories).
I added in an animation dummy, renamed it to StarterCharacter, and put it into StarterPlayer. I have LoadCharacterAppearance toggled under StarterPlayer, but they still just spawn in as the grey dummy. How do I make it so it applies their avatar appearance to the StarterCharacter when they spawn?

This is something i did for my own custom character, you could clone the players clothing and place them on a dummy then make the dummy the players character.
