How to use material qrcode icon in angular 8

Issue

I want to show a material icon in Angular 8. But it doesnt show

So i try to show the qrcode symbol like this:

<mat-icon class="patient-table-link patient-table-link-view material-icons"  [routerLink]="openEcheqSelectorQrcode(row.participantId)" routerLinkActive="router-link-active"  >qrcode-scan</mat-icon>

But it doesnt show the right icon.

But this works:

<mat-icon class="patient-table-link patient-table-link-view" [routerLink]="getViewLink(row.participantId)" routerLinkActive="router-link-active" >visibility</mat-icon>

``
So the library is installed correct

That the Qrcode symbol will be displayed.

Thank you

Solution

So solved!! angular material doesn't have such Icon. That is why I asked.
