Nested routes using drf-extensions are not documented in API docs

Question

I'm writing API in DRF and had need to add nested routes. Since drf-extensions are specified in official documentation I tend to use this package and it seemed to be working, but the documentation generated by Django Rest Framework doesn't include nested Viewset(route).

The documentation is generated using include_docs_urls from rest_framework.documentation

I would really like to have my nested endpoint described in generated documentation. Is it possible?

drf-extensions==0.5.0
