Issues with Implementing International Telephone Input with Country Flag Dropdown in Angular 16

I'm attempting to implement international telephone input functionality with a country flag dropdown in Angular 16. Initially, I tried using the "ngx-mat-intl-tel-input-v16" library, but encountered several issues including improper styles and malfunctioning search functionality.

After some research, I switched to the "ngx-intl-tel-input" library, but I'm facing difficulties getting it to work properly in my Angular 16 project. Despite following the documentation and examples provided, I haven't been successful in resolving the issues.

Here are the details of my project's package.json file:
