You can use the token to remove or replace the timer task.

Example

-- You can store the timer task token in a global variable and use it to acknowledge that the timer task is already registered.
if updateDataToken == nil then
    updateDataToken = MainLoopScheduler.prependTimer(
        MainLoopStage.USER,
        "UpdateDataObjects",
        TimerRecurrence.Recurring,
        millis(5),
        function()
            dataObjects.speed:setValue(currentSpeed)
        end
    )
end

Example

-- You can use the previously stored token to remove the timer task. Note that compared to a simple task, the stage does not need to be passed.
if updateDataToken ~= nil then
    MainLoopScheduler.removeTimer(updateDataToken)
    updateDataToken = nil
end
