how to rotate part to face camera direction?

I have a tool that makes a part that has a decal on it when the player clicks the mouse but the issues is that the part is always facing one direction and it never changes:

so my mission is to make the part face upwards depending on where the player's camera is facing when the mouse was clicked like this:

my code:

    local part = Instance.new("Part")
        part.Anchored = true
        part.CanCollide = false 
        part.Size = Vector3.new(7, 0.1, 7)
        part.Position = Vector3.new(0, 5, 0)
    part.Transparency=1
    part.CFrame = CFrame.new(position)
    part.Parent = workspace
