Annotations on model properties in SwaggerUI

I have built a ASP.Net Core 3.1 Web API, and I am interested in auto-generating documentation for my clients. I've followed the very simple instructions to install either NSwag or Swashbuckle in my project found here: Microsoft Docs and in both cases I can see documentation for my APIs, but there are no descriptions on the model properties.

Java seems to have an @ApiModelProperty annotation for this, but I don't see a similar attribute in .Net. Is it possible to add descriptions for Model properties in either of these swagger implementations, that would show up in Schema section in the Swagger UI?
