Describing requestBody parameters

I want to define my API endpoints with swagger OAS 3.0.0. My API requires quite a few parameter in the request body and I would like to give a detailed explanation for each request body parameter. The older version of OAS allows for "path" : { "endpoint" : { "in" : "body"}}} which would be perfect because I can describe each parameter individually. However, for OAS 3.0.0 it is stated that parameter in request body should be defined using the requestBody field which does not support description(ie what is the parameter referring to) for each parameter. Is there anyway for me to describe each request body parameter in OAS 3.0.0.?

    OpenAPI 3.0 supports the description field in the requestBody itself, the requestBody schema, and individual schema fields.
