I defined config as below - 
import { NgModule } from '@angular/core';
import { AuthModule } from 'angular-auth-oidc-client';


@NgModule({
  imports: [AuthModule.forRoot({
    config: {
      authority: 'https://login.microsoftonline.com/https://login.microsoftonline.com/<tenantid>/v2.0/v2.0',
      authWellknownEndpointUrl: 'https://login.microsoftonline.com/common/v2.0',
      redirectUrl: window.location.origin,
      clientId: '<clientid>',
      scope: 'user_impersonation openid profile offline_access',
      responseType: 'code',
      silentRenew: true,
      useRefreshToken: true,
      maxIdTokenIatOffsetAllowedInSeconds: 600,
      issValidationOff: false,
      autoUserInfo: false
    }
  })],
  exports: [AuthModule],
})
export class AuthConfigModule { }

Azure Ad is configured for single tenant but while using above config app calls common endpoint of azure ad.
While debugging found it uses default authWellKnownEndpoints from library.

Steps to reproduce the behavior

Create a new angular app with 15 or 18 version and use pkce flow with azure ad.

A clear and concise description of what you expected to happen.

It should use authroity url provided in config or there should be explanation of how to configure single tenant and multi tenant application for azure ad authentication.

solved above issue by supplying authWellknownEndpointUrl along with authority. authority is mandatory but it doesn't use authority while fetching config and authWellknownEndpointUrl is not mandatory but uses it instead.
