Please tell me how to make the api specification look better in swagger ui

Hello, I am currently writing an api specification through restdocs-api-spec-restassured.
Currently, there are too many api, so I want to divide the swagger page by schema.
or to have the description of the api folded when entering the specification
like https://petstore.swagger.io/ (If open specification, all api descriptions are open...)
Can you help me what to do?
