Expected behavior validate a mdb-file-upload with a reactive form

Actual behavior the mdb-file-upload don't have validation

Resources (screenshots, code snippets etc.) How can we validate the mdb-file-upload using a reactive form?

example using:

<mdb-file-upload #fileUpload
          [removeBtn]="'Delete'" [defaultMsg]="'Select a image'"
         [removeBtnDisabled]="true"
          (fileAdded)="onFileAdded($event)">
        </mdb-file-upload>

is it possible to include it in a formControlName? How can we validate that it has a selected file?
