Integration of Angular Website to Stripe API

I have an existing Membership Website that already works and displays basic information about the Member. I am looking to integrate this with Stripe using the API in order to collect annual membership payment. The backend has been written in .Net and the SetPaymentIntent is already returning a Client Secret. I am looking to implement something like https://stripe.com/docs/payments/quickstart?client=html but need assistance with the front-end. Full Windows test environment is ready to use (Visual Studio / Chrome / Postman). Some work was done by another developer but there were unable to complete the task.
