  ],
};

2. app.component.ts

@Component({
  imports: [MatTooltipModule, MatSidenavModule],

    <mat-drawer-container class="example-container">
      <mat-drawer mode="side" opened>Drawer content</mat-drawer>
      <mat-drawer-content>
        <div matTooltip="Hello">Hello</div>
      </mat-drawer-content>
    </mat-drawer-container>
  `,
