          </footer>
        </form>
      </cdk-step>

Any help is appreciated. Thanks you!

Answer 1

Reference your stepper and then call the following method at the appropriate time (this implementation assumes you are referencing the stepper from a parent component):

@ViewChild('cdkStepper') cdkStepper: MatStepper | undefined;

someMethod(){
  if(this.cdkStepper){
    this.cdkStepper.reset()
  }
}

Answer 2

After a while I found

<button class="mx-1 w-24" [size]="'md'" app-ui-button [variant]="'default'"
   (click)="isShowModalStepper = !isShowModalStepper; cdkStepper.reset()">
    Cancel
</button>
