How to get last 30 minutes active users?

[TharukaDananjaya]

I want to get last 30 minutes or want to get minutes range data :
`public function usersInLast30Minutes($propery_id)
{
try {
Config::set('analytics.property_id', $propery_id);

        $startTime = Carbon::now()->subMinutes(30);
        $endTime = Carbon::now();
        $period = Period::create($startTime, $endTime);
        return $this->getAnalyticsData($period, [
            'activeUsers'
        ], ['country']);
    } catch (\Throwable $th) {
        throw $th;
    }
}

/**-----------------------------------------------Common _--------------------------------- */

public function getAnalyticsData($period, $metrics = [], $dimensions = [], $limit = 10)
{

    // Get analytics data for each time range
    $analyticsData = [];
    try {
        $response = Analytics::get(
            $period,
            $metrics,
            $dimensions,
            $limit
        );

        return $response;
    } catch (InvalidPeriod $e) {
        // Handle invalid period exception
        throw $e;
    } catch (\Exception $e) {
        // Handle other exceptions
        throw $e;
    }

    return $analyticsData;
}`

Above method not work. i think its only work for date ranges not time ranges. Anyone know how to do that?
