Shifting attention to an angular 6 form field

I am developing an application in Angular which involves creating, reading, updating, and deleting user information. I have a requirement for the username to be unique and need to display an error message if it is not unique, while also focusing on the username field. I have successfully implemented the error handling but I am facing difficulties in setting the focus back to the username field.

Any assistance with this matter would be greatly appreciated.

Below is my TypeScript code:

export class AdduserComponent implements OnInit {

  constructor(
    private formBuilder: FormBuilder,
    private userService: UsersService,
    private router: Router,
    private snackBar: MatSnackBar
  ) { }

  addForm: FormGroup;
  passwordsMatcher = new RepeatPasswordEStateMatcher;

  ngOnInit() {
    // Form initialization logic
  }

  onSubmit() {
    // Form submission logic
  }

  changeClient(value) { }

  resetForm() {
    // Reset form function
  }
}

Below is the HTML code:

<div style="height: 100vh" fxLayout="column" fxLayoutAlign="center center">
  <mat-toolbar class="toolbar">
    <span class="span">Create New NI User</span>
  </mat-toolbar>
    <mat-card class="card">
        <mat-card-content>

    <!-- Form content goes here -->

  </mat-card-content>
    </mat-card>
</div>

If you want to set focus on an input field, you can utilize the focus() method of the HTMLInputElement. Simply assign a reference to your input element, such as #inputField, and access it in your code using ViewChild('inputField'):

<input #inputField matInput type="text" formControlName="fieldName" ...>
import { ElementRef, ViewChild } from '@angular/core';
...
@ViewChild('inputField') fieldRef: ElementRef;
...
fieldRef.nativeElement.focus();
