C# Azure AD and Anuglar Azure AD - one needs admin account

Question

I'm trying to create a PoC application set, WebApi with a Angular (other or variant frontend), using Azure AD to authenticate my Federation users.

I've got the backend working fine, with authentication/MFA working as expected, and showing sign-in prompts.

I can get the login screen to pop-up (and with the correct tenant), however when I try sign-in, I get a admin-access required - am I requesting too much scope?

This is my app.module.ts code from the sample, where

import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';

import { AppComponent } from './app.component';
import { LoginComponent } from './partials/login/login.component';
import { MsalModule, MsalInterceptor } from '@azure/msal-angular';
import { HTTP_INTERCEPTORS } from '@angular/common/http';
import { AppRoutingModule } from './app-routing.module';

@NgModule({
  declarations: [
    AppComponent,
    LoginComponent
  ],
  imports: [
    MsalModule.forRoot({
      clientID: "my-client-id",
      authority: "https://login.microsoftonline.com/my-tenant-id",
      redirectUri: "http://localhost:4200/",
      validateAuthority : false,
      cacheLocation : "sessionStorage",
      storeAuthStateInCookie: false, // dynamically set to true when IE11
      postLogoutRedirectUri: "http://localhost:4200/",
      navigateToLoginRequestUrl : true,
      popUp: false,
    }),
    BrowserModule,
    AppRoutingModule,
  ],
  providers: [{
    provide: HTTP_INTERCEPTORS,
    useClass: MsalInterceptor,
    multi: true
  }
  ],
  bootstrap: [AppComponent]
})
export class AppModule { }

Please check if your Azure AD app has any permissions which require admin consent on Azure portal:

If yes, please click on the "Grant admin consent for **" at the bottom.

If no, go to Admin Centers > Azure AD > Users > User Settings > Enterprise applications - User settings then make sure "Users can consent to apps accessing company data on their behalf" is enabled.
