I'm trying to implement recaptcha enterprise in angular 12, but documentation is not being clear, I implemented it in the class according to the documentation link, but the method does not return the token in $event
<form [formGroup]="partnerForm" (ngSubmit)="becomePartner($event)" #partnerFormEl="ngForm" method="POST">
<button id="demo-form" class="g-recaptcha"
data-sitekey="6LeCCoYfAAA..."
data-callback='becomePartner'
data-action='submit'>Submit</button>
</form>I need a light on this documentation, any example already implemented?
