How do I make this script ONLY run if the player is on a certain team in the game such as "Chief"

local Opened = script.Parent.Opened

function Open(Part, Type)
    if Opened.Value == false then
        if game.Players:FindFirstChild(Part.Parent.Name) or game.Players:FindFirstChild(Part.Parent.Parent.Name) then
            Opened.Value = true
            for i = 0.1,5.4, 0.1 do
                script.Parent.DoorLeft.CFrame = script.Parent.DoorLeft.CFrame * CFrame.new(0.1,0,0)
                script.Parent.DoorRight.CFrame = script.Parent.DoorRight.CFrame * CFrame.new(-0.1,0,0)
                wait()
            end
            wait(script.Parent.WaitTime.Value)
            for i = 0.1,5.4, 0.1 do
                script.Parent.DoorLeft.CFrame = script.Parent.DoorLeft.CFrame * CFrame.new(-0.1,0,0)
                script.Parent.DoorRight.CFrame = script.Parent.DoorRight.CFrame * CFrame.new(0.1,0,0)
                wait()
            end
            Opened.Value = false
        end
    end
end

script.Parent.Field1.Touched:connect(Open)
script.Parent.Field2.Touched:connect(Open)
