Description
How can we help?
Currently, after reading the documentation, for showing extensions found in the schema, you can do that with the showExtensions property, but only for Operations/Parameters/Response/Schema objects. The problem is that there are some schemas that have extensions at the top-level or path level ( eg. shown in the screenshot below ) and they are not shown by default.

I've tried to access the data of the extension through SwaggerUI plugins, but only managed to do so at the operation level with wrapComponents -> operation. Are there any examples or could you provide some help on how I can access the extension data through plugins if the extension is at top-level or path level?

Research direction
Start by reviewing the documented showExtensions property and the SwaggerUI plugin entry point using wrapComponents -> operation. Determine how top-level and path-level extension data can be accessed, then verify that the resulting approach exposes the extensions shown in the schema screenshot.
