I'm sorry, but the extracts provided do not contain the specific code for the self-service example on port 4455. However, Ory provides several examples of self-service flows in different languages and frameworks. You can find these examples on the Ory GitHub repositories linked in the extracts. Here are a few: - [Browser UI, Golang (API Flow), Express.js, React.js, React Native](https://github.com/ory/kratos-selfservice-ui-node/tree/master/src/routes) - [Verification View, Generic Form View, Example Input Form Element](https://github.com/ory/kratos-selfservice-ui-node/tree/master/views/partials) - [React Next.js](https://github.com/ory/kratos-selfservice-ui-react-nextjs) - [Go](https://github.com/ory/kratos/tree/master/examples/go/selfservice/verification) - [React Native](https://github.com/ory/kratos-selfservice-ui-react-native/tree/master/src/components) Please note that you need to implement the HTML code in your solution, which gives you complete flexibility and customizability in your user interface flows and designs. This part of your application then directly interfaces with Ory Identities through the API. The API responds with a JSON document describing the form elements to render and actions the form should take upon submission, cancellation, etc. For more detailed information, you can refer to the [Ory documentation](https://www.ory.sh/docs/kratos/self-service/flows/verify-email-account-activation).
