Do you have any direction to use "setTintFill" to creature object in phaser 3

[ak3dkung]

I want to change the color programmatically to game object .
default function name is "setFillTint" (phaser3.24)
.
or any other way to change color of creature object? (just replace color to it)

do you have any suggestion the way to edit/add new function to doing this? (this function is very important to me, I have to make it success no matter what T_T)
