Missing import for ion component in typescript

Ionic Framework
1

I use ionic-framework in my project and import this module from index.html

<script type="module" src="https://cdn.jsdelivr.net/npm/@ionic/core@6.0.12/dist/ionic/ionic.esm.js"></script>

but when coding in my project in vs code, lit-plugin say

Missing import for <ion-content>
  You can disable this check by disabling the 'no-missing-import' rule.lit-plugin(no-missing-import)(2312)

I don’t import ionic in typescript file [import it in HTML file]

According to my experience working with other web components
Probably, the problem will be solved by importing this line into the typescript file
but how?

interface HTMLElementTagNameMap {
  "ion-title": HTMLIonTitleElement;
}
