Rotation Issue in Godot 4.1 with CharacterBody3D

I'm working on a 2.5D game in Godot version 4.1.stable. In my code, I have a character body that I want to rotate based on input. I'm using a Vector3i variable called current to store the rotation angles for the x-axis and y-axis. The problem is that the rotations don't seem to be applied correctly. When I print the current variable, it always shows as (0, 0, 0).

My code:

extends CharacterBody3D

var current = Vector3i.ZERO
var count = 0

func rotation(rotate_x: bool, key: String, angle: int,):
		if rotate_x:
			if Input.is_action_pressed(key):
					current.x = angle
					rotate_x(angle)
		else:
			if Input.is_action_pressed(key):
					current.y = angle
					rotate_y(angle)

func rotating():
	rotation(true, "Right", 90)
	rotation(false, "Left", -90)
	rotation(true, "Up", 90)
	rotation(false, "Down", -90)

#Output the inputs
func _input(event):
	if Input.is_anything_pressed():
		print(current)

The output:
(0, 0, 0)
