Why can I not toggle on/off this while loop when triggering a server event?

Greetings. Another day, another problem. The goal here is to write a ServerEvent (for say an action for a character) that loops infinitely (like spinning or something), but can be toggled off. I set it up in a ways so that it syncs with a local script that will send either a 'true' or 'false' statement (hense the Toggle var in the function).

The problem here is I can get the loop to start on ServerEvent connect, however getting it to stop has proved fruitless.

script.Parent.onServerEvent:Connect(function(Player, Toggle)
    local bool = Toggle
    if bool == true then
        while wait() do
            print("This is looped!")
        end
    end
    if bool == false then
        print("No more loop!")
    end
end

This is a example script I wrote to summarize what I'm trying to achieve. Any help would be appreciated!

EDIT: I did eventually figure it out! I used a BoolValue that was stowed away inside the Character, and then had the repeat until wait for that to go false, to turn everything off. I was however put in the right direction by the fine fellow theking48989987. Thank you!
