[ObjC] What parameter changes the name of the generated pod spec? The command I'm using says that -p package-name is incorrect

Description

I want to name the output of running the swagger codegen tool to have the pod name (and the top level file called) not OpenAPIClient. I want it to be something else. I managed to this in Java by running the command.

npx openapi-generator generate -i afs.json -g java -D apiPackage=org.package.name --model-package org.package.name --artifact-id artifactID -o "Path"

and this generates the correct packages and names.

I'm not sure how to do this in ObjC. I thought I would need to do

npx openapi-generator generate -i afs.json -g objc -D apiPackage=org.package.name.api --model-package org.package.name.models --artifact-id artifactID-p --package-name f -o D:\codegen\

however that tells me that this is an incorrect parameter. There's no information I can find about how to do this.

Start with the ObjC generator's command-line options and compare them with the example command using afs.json and -o. Confirm which supported option controls the generated pod name and top-level file, then document the valid invocation or clarify that no such option exists.
