How to Replace PermissionManagementComponent

Permission management modal

Run the following command in angular folder to create a new component called PermissionManagementComponent.

yarn ng generate component permission-management --inlineStyle

Open the generated permission-management.component.ts in src/app/permission-management folder and replace the content with the following:

import { ConfigStateService, CurrentUserDto, ReplaceableComponents } from '@abp/ng.core';
import {
  GetPermissionListResultDto,
  PermissionGrantInfoDto, PermissionGroupDto, PermissionManagement, PermissionsService, ProviderInfoDto, UpdatePermissionDto

import { finalize, switchMap, tap } from 'rxjs/operators';
