How to add a button in a mat-select option when an option is selected?

I'm trying to add a url button next to an mat-select option when it is selected. Clicking that button will open a new tab with info related to that option. I don't want all options to have this button when the mat-select is dropped down, just when it is selected.

I'm having trouble finding a solution for this. Does anyone how I can accomplish this?

<mat-select [formControl]="formControl" (optionSelected)="onSelected($event)">
<mat-option></mat-option>
@for (option of options; track option) {
<mat-option [value]="option.value">
{{option.key}}
<button (click)="openLink()">Open<button> <!-- only want this when it is selected -->
</mat-option>
}
</mat-select>
