If I have a url fragment, I would like angular to scroll to that specific section, but this has to be turned on in angular router module.
http://localhost:3000/admin/extensions/common/test#1234
http://localhost:3000/admin/extensions/common/test#4567

https://angular.io/api/router/ExtraOptions#anchorScrolling
e.g.

@NgModule({
    declarations: [],
    imports: [
        CommonModule,
        AppComponentModule,
        RouterModule.forRoot(routes, { useHash: false, relativeLinkResolution: 'legacy', **anchorScrolling: 'enabled'** }),
    ],
    providers: [],
    bootstrap: [AppComponent],
})
export class AppModule {}

can we add this in angular?
