How to integrate custom widget with custom self-hosted developer portal.

We are able to create and host the custom widget in managed self-hosted developer portal but in order to integrate the custom widget with custom developer portal we did not find any solution. Any document or code will help to fix the problem. Thanks

The issue names no file, test, or entry point. Start by locating the custom widget and custom self-hosted developer portal integration paths in the TypeScript repository, then review the existing developer portal documentation. Done means providing a documented, reproducible integration path or clearly identifying the missing implementation guidance.
