how do i reset the repeated functions?

this is kinda hard to make a question about cuz i dont really know what the question should be but heres the context. im trying to make a model rotate left when left shift is pressed and when left shift is pressed again it turns right and it repeats kind of like left right left right left right

this is the code

local DisconnectRemoteEvent = true local RotateModel_Left = true

local function RotateTheModel_Left()
    workspace.Model:SetPrimaryPartCFrame(workspace.Model:GetPrimaryPartCFrame()*CFrame.fromEulerAnglesXYZ(0,0.025,0))
end
local function RotateTheModel_Right()
    workspace.Model:SetPrimaryPartCFrame(workspace.Model:GetPrimaryPartCFrame()*CFrame.fromEulerAnglesXYZ(0,-0.025,0))
end

RemoteEvent.OnServerEvent:Connect(function() 
    DisconnectRemoteEvent = false
    repeat wait()
        if RotateModel_Left == true then
            RotateTheModel_Left()print("Ok!")
        else
            RotateTheModel_Right()print("Ok!!!")
        end
    until DisconnectRemoteEvent == true print("HOLY ")
    RotateModel_Left = false
end)

game.ReplicatedStorage.RemoteEvent.OnServerEvent:Connect(function()
    DisconnectRemoteEvent = true print("SON ")
end)

im stuck on line 19 above where i dont really know what to do and im trying to do something similar to the code below that i made(line 11 and line 17) to loop the directioin the model is turning

the problem is the code above just makes the model turn left once,stops then turn right once,stops and now you can only do turn right,stop and the loop doesnt repeat and i have no idea how to get pass line 19 to make it loop left and right

Note:the code below works perfectly fine by the way

local RemoteEvent = game.ReplicatedStorage.RemoteEvent1
local REMOTEEVENT = game.ReplicatedStorage.RemoteEvent2
local True = true local False = false

RemoteEvent.OnServerEvent:Connect(function() local Model = workspace.model
    if False == false then
        while True do
            Model:SetPrimaryPartCFrame(Model:GetPrimaryPartCFrame()*CFrame.fromEulerAnglesXYZ(0,0.025,0))
            wait()
        end
        False = true
    else
        while True do
            Model:SetPrimaryPartCFrame(Model:GetPrimaryPartCFrame()*CFrame.fromEulerAnglesXYZ(0,-0.025,0))
            wait()
        end
        False = false
    end
end)

REMOTEEVENT.OnServerEvent:Connect(function()
    True = false
    wait()
    True = true 
end)

i swapped to using repeat loops cuz i thought it would reduce the number of steps the game needs to run(which means it runs faster) and since i dont really know how to read steps the code is taking i just took a path that might have less moving parts but i dont know if its true or not

i do know what the code is doing

any tips would be cool
