Why <ion-button> is not working in ionic 5 with sidemenu framework

Ionic Framework
1

I have created a new ionic app with sidemenu.

But now im trying to add tag, but its not working. The error is below

Error: Template parse errors:
‘ion-button’ is not a known element:

  1. If ‘ion-button’ is an Angular component, then verify that it is part of this module.
  2. If ‘ion-button’ is a Web Component then add ‘CUSTOM_ELEMENTS_SCHEMA’ to the ‘@NgModule.schemas’ of this component to suppress this message. ("

Could you please help me

You are likely missing an import in app.module.ts (ionicmodule)

And the module related to the component? Include formsmodule too?
