Hello. You can download Swagger UI and place it within your project.
For a quick implementation, I would suggest trying the plain HTML route (the directions are at the bottom of this link)
Once you have that in your site (maybe in the resources folder or wherever makes sense for you), just update the Swagger path in the index.html file to point to your Swagger JSON
If you see any errors, make sure that the Swagger file is able to load properly. Thanks!
