im doing a backrooms game and i want it realistic as possibble but i cant connect the bobbing and the tween service for crouching how can i do it

crouchTweenInfo = TweenInfo.new(0.35, Enum.EasingStyle.Quad, Enum.EasingDirection.InOut)

Player.CameraMode = Enum.CameraMode.LockFirstPerson


function CrSway()
	local goal = {}
	if Humanoid then
		if CrouchEnabled == false then
			goal.CameraOffset = Vector3.new(0,-0.5,0)
		elseif CrouchEnabled == true then
			goal.CameraOffset = Vector3.new(0,-3,0)
		end
	end
	
	local crouchTween = TweenService:Create(Humanoid, crouchTweenInfo, goal)
	crouchTween:Play()
end
