Fe Gun Kit Viewmodel Custom Character Problem

Hi, I use Fe Gun Kit in my game. I examined the scripts and noticed that in order for the viewmodel used in the fps view to be the same as the shirt worn by the player, a new shirt was created in the viewmodel and the same id was copied into it. But when I put a custom character into the starterplayer, the default viewmodel of the game appears on the screen (as in the photo). What can I do to have the shirt of the character I put in the starterplayer cloned into the viewmodel?
(The first photo is what I don’t want, and the second photo is what I want it to be.)
Thank You…
