If a URL you're trying to reference is partially model-generated, the link output by ChatGPT won't be clickable.
To make a link clickable, your custom action will need to output the full, qualified URL for the model to reference. A fully qualified URL includes all necessary components, including the scheme (http or https), domain, path and any query parameters.
If you want clickable links, do the following:
Check URL format: Ensure the URL starts with "http://" or "https://".
Validate domain and path: Confirm the domain is correctly spelled and the path accurately leads to the intended content.
Review the custom action's URL generation: If the URL is dynamically generated, review your action to ensure it constructs the URL correctly.
