Azure Service fabric Actor reminders are not triggering at given time interval

Question

I want to create one fabric service which runs at a specific time irrespective of its execution time.

I have created a fabric service with actor reminders and set a period to run every 3 minutes. In the call-back function, I have put a delay of 2 minutes as function processing time.

My code looks like below

 public async Task ReceiveReminderAsync(string reminderName, byte[] state, TimeSpan dueTime, TimeSpan period)
    {
        var current = DateTime.Now;
        if (reminderName.Equals("TaskReminder"))
        {
            Thread.Sleep(2 * 60 * 1000);
            using (var writer = File.AppendText("actor.txt"))
            {
                await writer.WriteLineAsync("1 :: " + current.ToString() + " --> " + DateTime.Now.ToString());
            }
        }
    }
    protected override async Task OnActivateAsync()
    {
        await RegisterReminderAsync("TaskReminder", null, TimeSpan.FromSeconds(10), TimeSpan.FromMinutes(3));

    }

And my logs in Actor.txt looks like below

1 :: 12/28/2021 4:54:52 PM --> 12/28/2021 4:56:52 PM
1 :: 12/28/2021 4:59:52 PM --> 12/28/2021 5:01:52 PM
1 :: 12/28/2021 5:05:52 PM --> 12/28/2021 5:07:52 PM

I want it to run every 3 minutes but it's adding function execution time(2 minutes) and running at every 5 minutes instead.
