I am trying to open nebular 'stepper' step, which depends on query params. For example: if route is /products/create?step=third shoud open third step
<nb-stepper [selected]="'second'">
  <nb-step [stepControl]="firstForm" [label]="first" #first>
   first
  </nb-step>
  <nb-step [label]="second" #second>
    second
  </nb-step>
  <nb-step [label]="third" #third>
    third
    <ng-template #third>Third step</ng-template>
  </nb-step>
</nb-stepper>
i have tried to use selected property, but it did not help
