Using Injected Token to configure a lazily loaded module

Question

Consider the following snippet. How do I access the provided value of Environment in forRoot? Is there an alternate way that I do the same?

interface Environment {
  tokens: Record<string, string>;
}

const ENVIRONMENT = new InjectionToken<Environment>('ENVIRONMENT');

// `SomeModule` with `forRoot` to configure it. This module is from an external library.

// Some library module that I'm creating
@NgModule({
  imports: SomeModule.forRoot() // `tokens` needs to passed here.
})
export class MyLibraryModule {}

MyLibraryModule will be consumed in some application where ENVIRONMENT will be injected. It will be lazily loaded
