In my Angular application I need to use 2 Error handler, the first one is my custom error handler and second one is the [Elastic error handler](https://www.elastic.co/guide/en/apm/agent/rum-js/current/angular-integration.html). Can I use both?

Right now I see that the last one I register in app.module overwrite the previous one, and it is not possible to use `multi: true` like the interceptor.

```auto
        providers: [
        {
          provide: ErrorHandler,
          useClass: CustomErrorHandler
        },
        {
          provide: ErrorHandler,
          useClass: ApmErrorHandler
        },
      ]

```

Thanks very much
