Use Web Components in Vue 2 and 3 + Composition API

This summary provides a comprehensive overview of incorporating Web Components into a Vue application, covering both Vue 2 and Vue 3 versions. In Vue 2, the `ignoredElements` array is used to let the application know that a Web Component is present, while in Vue 3, the `config.isCustomElement` function is used instead. The Composition API introduces new features such as tracking values with the `ref` function and accessing component methods using the `value` property. Additionally, the Vonage Verify API can be integrated into a Vue application to provide a secure verification process for users. The integration involves creating a custom Web Component that communicates with the server-side API to send and verify security codes. Overall, this summary highlights the key points of incorporating Web Components into a Vue application and demonstrates how to use the Vonage Verify API in a real-world example.
