3. Import InspectorModule from @ngneat/inspector in your project's root module's imports section. This can be skipped with --skipImport.

👉 Please note: @ngneat/inspector is a debugging tool and it helps you to develop faster. So, it shouldn't be part of your production deployment. When you install it using ng add @ngneat/inspector it is already taken care for you, as it writes import statement like this: imports: [environment.production ? [] : InspectorModule.forRoot()]
