Subscribe to events using webhooks

Question

We're using MS Graph Subscription for events via webhooks. We're only interested in reminder events and want to ignore all other event notifications like create / update of a calendar event.

1. Is there a way to provide a filter condition to only subscribe for reminder events?
2. Or in the event response / decrypted resource data is there a field which can be used for checking reminder resource type ?

Subscription subscription = new Subscription();
subscription.setChangeType("created,updated,deleted");
subscription.setNotificationUrl(notificationUrl);
subscription.setResource("/me/events?$select=id,subject,start,end,webLink,onlineMeetingUrl,reminderMinutesBeforeStart");
subscription.setExpirationDateTime(java.time.OffsetDateTime.now().plusDays(3));
subscription.setClientState(CLIENT_STATE);
subscription.setEncryptionCertificateId(certificateStore.getCertificateId());
subscription.setEncryptionCertificate(certificateStore.getBase64EncodedCertificate());
subscription.setIncludeResourceData(true);

subscription = graphClient.subscriptions()
        .post(subscription);
