Is there a way to rotate a body part using events? (1.15.2)

Hello, I'm trying to create an event so when the player presses P it rotates the right arm so it looks like he's pointing at something and I've already created a keybind but it doesn't rotate the arm.

Here's my Event code: 

@Mod.EventBusSubscriber(modid = Main.MOD_ID, bus = Bus.FORGE) 
public class PointEvent { 
  	@SubscribeEvent 
  	public static void pointEvent(RenderPlayerEvent event) { 
    	PlayerEntity player = event.getPlayer(); 
    	if(Keybind.LIFT.isKeyDown()) { 
      		Main.LOGGER.info("Rotated Arm!"); 
      		event.getRenderer().getEntityModel().bipedRightArm.rotateAngleX = 0.5F; 
    	} 
  	} 
}

And here's the keybind code:

public class Keybind { 
	public static final KeyBinding LIFT; 
	public static void init() { 
		ClientRegistry.registerKeyBinding(Keybind.LIFT); 
	}

	static { 
		LIFT = new KeyBinding("imam.key.lift", 80, "key.categories.imam"); 
	} 
}
