public selectCampaign(): void {
  this.steppers.showFeedback('Checking, please wait ...');
  this.steppers.next();
}

Detailed service operations bellow:

Method	Description	Returns
`next()`	Complete the current step and move one to the next. Using this method on editable steps (in linear stepper) it will search by the next step without "completed" state to move. When invoked it dispatch the event onstepcomplete to the step element.	boolean - True if move and false if not move (e.g. On the last step)
`back()`	Move to the previous step without change the state of current step. Using this method in linear stepper it will check if previous step is editable to move.	boolean - True if move and false if not move (e.g. On the first step)
`skip()`	Move to the next step without change the state of current step. This method works only in optional steps.	boolean - True if move and false if not move (e.g. On non-optional step)
`goto(stepNumber: number)`	Move "active" to specified step id parameter. The id used as reference is the integer number shown on the label of each step (e.g. 2).	boolean - True if move and false if not move (e.g. On id not found)
`error(message: string)`	Defines the current step state to "error" and shows the message parameter on title message element.When invoked it dispatch the event onsteperror to the step element.	{string} message The error message
`clearError()`	Defines the current step state to "normal" and removes the message parameter on title message element.	void
`showFeedback(message?: string)`	Shows a feedback message and a loading indicador.	void
`clearFeedback()`	Removes the feedback.	void

import {DomSanitizer} from '@angular/platform-browser';
import {MatIconRegistry} from '@angular/material';

public options: StepperOptions = {
  enableSvgIcon: true
};

constructor(private _iconRegistry: MatIconRegistry,private _sanitizer: DomSanitizer) {}

public ngOnInit(): void {
  this._iconRegistry
    .addSvgIcon('step-done', this._sanitizer.bypassSecurityTrustResourceUrl('YOUR_ICON_URL'));
  this._iconRegistry
