Clarification on Generative AI Feature Availability in Copilot Studio

I am seeking clarification regarding the availability of the Generative AI feature in Microsoft Copilot Studio.

While exploring the trial license for Copilot Studio in our environment, I noticed that the feature is labeled as "Preview" in the interface. However, according to the Microsoft documentation on the official site (specifically the planned features for Microsoft Copilot Studio 2024 Wave 1), this feature is mentioned as being generally available (GA) starting April 30, 2024.

I have attached screenshots from both the Copilot Studio interface and the relevant documentation page for your reference.

Could you kindly reach out to the appropriate Microsoft channel partner and confirm whether the Generative AI feature is fully GA for all customers? If its availability is limited to specific licensing tiers or configurations, I’d appreciate details on that as well. Additionally, if there are steps we need to take to access the GA version, please advise.
