Yes, it is possible to call the service worker push event from your custom service in Angular. Here's a general outline of the steps you can follow:

1. Register the service worker: First, make sure you have a service worker registered in your Angular app. This can be done using the ngsw-config.json file or by manually registering the service worker in your main.ts file.
2. Implement the Push Notification functionality: Set up the necessary code to handle push notifications in your service worker file. This includes handling the push event and displaying the notification.
3. Create a custom service: In your Angular app, create a custom service where you can define the logic to trigger the push event. This service will communicate with the service worker and initiate the push notification.
4. Communicate with the service worker: To trigger the push event, you can use the ServiceWorkerRegistration object available in the browser's navigator object. You can access this object in your custom service and call methods like getRegistration() to retrieve the service worker registration and then interact with it.
5. Trigger the push event: Once you have the service worker registration, you can call the showNotification() method on the PushManager interface to trigger the push event and display the notification.

Remember to handle the necessary permissions and user consent for push notifications, as well as the data payload to be sent with the push notification.

Please note that the exact implementation details may vary depending on your specific use case and the version of Angular you are using, so you may need to refer to the Angular documentation and the documentation for the specific service worker library you are using for more detailed instructions.
