Have you tried working with the following block of code found on
BotDetect CAPTCHA Angular Module (TypeScript: Angular 2/4/5/6/7/8+)[^]

C#

export class YourFormWithCaptchaComponent {
// uncomment the line bellow if you use Angular 2/4/5/6/7
// @ViewChild(CaptchaComponent) captchaComponent: CaptchaComponent;

// uncomment the line bellow if you use Angular 8
//@ViewChild(CaptchaComponent, { static: true }) captchaComponent: CaptchaComponent;
