Stepper should provide an click event for step changes

Bug, feature request, or proposal:
Feature request

What is the expected behavior?
Add an click event that gets triggered when the step is clicked in the stepper component

What is the current behavior?
There's no such event.

What are the steps to reproduce?
NA

What is the use-case or motivation for changing an existing behavior?
We have some business logic that we need to save at each step. We have to show the message on click of step "Are you confirm?", we implemented with button click but unable to do in step click, and it's moving forward to next step on clicking of step.

Which versions of Angular, Material, OS, TypeScript, browsers are affected?
Angular 9+
Angular material 11.2

Is there anything else we should know?
Tried to use selectionChange event, no use.its working after the click event. i want to show or prevent before the change event.

needs to add click event on step like above. As of there is no option like that

Repérez l’implémentation du stepper Angular Material derrière mat-horizontal-stepper et mat-step, puis suivez les chemins de navigation de selectionChange et step-click. Examinez les tests pertinents du stepper s’ils sont disponibles ; le travail est terminé lorsque l’interaction demandée avec le step est couverte et prend en charge le comportement de confirmation ou de prévention décrit dans l’issue.
