MacOS Work With feature not available

How do I enable the beta “Work With” feature in the macOS client? The features are documented here, https://help.openai.com/en/articles/10119604-work-with-apps-on-macos but I do not see such options in my client. My client is on the latest with
1.2024.348.

It appears this feature is conditional on whether or not the user is a paying customer. It may be helpful for others if the documentation were updated to reflect this requirement.
