How do I get the Y position from a perlin noise if I have the X and Y coordinates?

I’ve got this code idk if it helps


function Wave:Update()
	for _,v in pairs(self._bones) do
		local WorldPos = v.WorldPosition
		local Settings = self._settings
		local Direction = Settings.Direction
		
		if Direction == EmptyVector2 then
			-- Use Perlin Noise
			local Noise = self._noise[v]
			local NoiseX = Noise and self._noise[v].X
			local NoiseZ = Noise and self._noise[v].Z
			local NoiseModifier = 1 -- If you want more of a consistent direction, change this number to something bigger
			
			if not Noise then
				self._noise[v] = {}
				-- Uses perlin noise to generate smooth transitions between random directions in the waves
				NoiseX = math_noise(WorldPos.X/NoiseModifier,WorldPos.Z/NoiseModifier,1)
				NoiseZ = math_noise(WorldPos.X/NoiseModifier,WorldPos.Z/NoiseModifier,0)
				
				self. _noise[v].X = NoiseX
				self._noise[v].Z = NoiseZ
			end
			
			Direction = Vector2.new(NoiseX,NoiseZ)
		else
			Direction = GetDirection(Settings,WorldPos)
		end
		
		v.Transform = newCFrame(Gerstner(WorldPos,Settings.WaveLength,Direction,Settings.Steepness,Settings.Gravity,self._time))
	end
end

I just want to basically
have a function that you put in the X and Z and then ur given the Y because the system looks at the math noise thing and outputs.

local Part = workspace.Part

local function Perlin2D(X, Y, Seed)
	local Z = (1 + math.noise(X, Y, Seed)/2)
	return Z
end

print(Perlin2D(Part.Position.X, Part.Position.Y, math.random()))
