Annotating the `GET /entity` (ie GetCollection) query for a resource that extends ` %pkg.isc.rest.model.resource`

Hi, we have defined a resource that extends `%pkg.isc.rest.model.resource`. We have our own custom query parameters that our resource uses in
```objectscript
GetCollection(ByRef params, selectMode As %Integer)
```
We need to document this method so that we can describe the set of valid query parameters.
How can we document this method so that the Open API generator will produce this custom documentation?

Can we create an action map whose name is null?
```objectscript

```
