I don't know what you guys are doing with your Angular buttons, or if you haven't looked at it since AngularJS (which I never used, so I don't know what it took there).

Adding a button to Angular is just adding a <button> to your template. If you want to use Angular Material, that's one additional import in your component's code file, and one additional attribute for that template's <button> element.

  import {MatButtonModule} from '@angular/material/button';

  <button matButton (click)="onClick()">Click me!</button>

Just at least have a look at the documentation or tutorial before spreading fibs like that.
