Why does Google Meet Report Audit Logs API not synchronous?

Question

I'm trying to use Google Meet Audit Activity Events API to get the report of the meeting room activities. But as i can see that the result is not match with the real, for example: I start a new meeting room, and stay in the room for about 5 minutes, but after joined room for 2 minutes and also after all people leave the room, i run the https://admin.googleapis.com/admin/reports/v1/activity/users/all/applications/meet?eventName=call_ended, there is no any records was returned, i have to wait for a couple minutes or more than 5 minutes later, the report with that URL will return full data. Is this a bug of Google or because of my PHP script having a problem? Is there anyway to get the report realtime when the meeting is ocurring?

Here is my sample script:

$client = $this->getClient();
$client->addScope('https://www.googleapis.com/auth/admin.reports.audit.readonly');
$client->setSubject('<email_of_user>');
$service            = new Google\Service\Reports($this->client);
$userKey            = 'all';
$applicationName    = 'meet';
$optParams          = Array('eventName' => $eventName);

$reports = $service->activities->listActivities($userKey, $applicationName, $optParams);
print_r($reports->getItem());
exit();

This is expected behaviour, it takes a certain amount of time for the new data to propagate across the system before it's available via the API.

The data isn't available 'real-time', as in it will not reflect the state of the meeting at the exact moment of the request - the API returns a saved report of the meeting activity rather than directly fetching the information live from the room. The same can be said for all Workspace APIs.
