you could just use the render 2 library [remove/set](https://angular.io/api/core/Renderer2#setAttribute) attribute library for this edit: cant actually do this, just use ``` Text Text" ```

it seems this cant actually be done using setAttribute since mat-button seems to be a [directive](https://material.angular.io/components/button/api#directives) why not just use ngIf, this is usually the most common way to address...
