Publishing to private programmatically API call

[Rain Cao]

Hello. 

I have been following this document on using the APIs to update and publish Chrome extensions. For publish I see you can set the parameter as trustedTesters or default. However, I want to publish the item to users in my organization only (private option if done manually). Is there a way to do so?
I inquired ChatGPT and it tells me to use publishVisibility and restrictedDomains. However I did not find those fields in the API doc, so perhaps it was obsolete?

Thanks!

I've been using the API to publish a mix of public and private extensions, and I've found that if you do not include the publishTarget parameter, then the extension's visibility setting will remain unchanged.
