// sleep function is updated as below
func sleepForWait(ctx context.Context,t time.Duration) {
		select {
	case <-ctx.Done():
		return
	case <-time.After(t):
		return
	}
}

//We will use context to cancel the sleeping process
ctx, cancel := context.WithCancel(context.Background())
//Now we can just call it to wait for 5 min
sleepForWait(ctx,5 * time.Minute)


// We will save this function in a variable and when user hits stop we will call this functions
// it will close the channel and triger ctx.Done() case to execute, Hence return
cancel()
