1 form 2 submit buttons Angular 5 - html

Question

So I have one form and I need two submit buttons, i need the ngNativeValidate to validate it, how can I get the value of the button that submitted the form in the onClickResolveTramite()?
It looks simples but I've searched for it and found nothing, i just need a true or false to know if it's approved or not.
<div class="modal-body">
<form (ngSubmit)="onClickResolveTramite(form)"
#form="ngForm"
id="resolveTraimte"
ngNativeValidate
autocomplete="off">
<!-- STATUS -->
<div class="form-row">
<div class="form-group col">
<label for="message">
Reason
</label>
<span>*</span>
<textarea class="form-control"
name="message"
rows="4"
id="message"
[(ngModel)]="tramite.message"
placeholder="Reason"
required></textarea>
</div>
</div>
<div class="form-row">
<div class="form-group col">
<label for="user">
User
<span>*</span>
</label>
<select class="form-control"
name="user"
id="user"
[(ngModel)]="user"
required>
<option *ngFor="let user of tramite.users"
[ngValue]="user">
{{user.nome}}
</option>
</select>
</div>
</div>
</form>
</div>
<div class="modal-footer"
style="border: none;">
<button class="btn btn-light"
(click)="onClickclose()">
Cancel
</button>
<button *ngIf="tramite.needApro"
type="submit"
form="resolveTraimte"
class="btn btn-danger"
name="submitTramite"
value="repprove"
formaction="repprove">
Repprove
</button>
<button class="btn btn-success"
type="submit"
name="submitTramite"
form="resolveTraimte"
value="approve"
formaction="approve">
{{ tramite.needApro ? 'Approve' : 'Complete' }}
</button>
// Controller
onClickResolveTramite(form: NgForm) {
console.log(form);
}

Assign different id to each button. Then you can obtain id of button which triggered submit using
document.activeElement.id
