I am currently learning ReactJS and encountering an issue when using jQuery with React JS for intlTelInput. I have installed npm jQuery and imported all the necessary code. Additionally, I have included all the required CSS and jQuery links in my index.html file, but the code is still not functioning properly, resulting in the following error:
TypeError: window.intlTelInput is not a function
If anyone has any insights or solutions to this problem, I would greatly appreciate your assistance in resolving it.
Below is the snippet from my Index.html page where I have added all the CDN links:

Notice the use of %PUBLIC_URL% in the tags above.
It will be replaced with the URL of the `public` folder during the build.
Only files inside the `public` folder can be referenced from the HTML.
Unlike "/favicon.ico" or "favicon.ico", "%PUBLIC_URL%/favicon.ico" will
work correctly both with client-side routing and a non-root public URL.
Learn how to configure a non-root public URL by running `npm run build`.
