Microsoft 365 Copilot Chat and Agent Starter Kit

CynthiaJohnsonI have tried to follow all of the steps in your IT guide and I still cannot get the "create an agent" button to appear for our end users in M365 Copilot Chat.  I've opened multiple tickets with support, and they are also completely stumped.  Are these capabilities fully rolled out to all tenants or is that still in progress and I just need to wait?  Any help you can provide would be appreciated.  My users are VERY eager to start making agents.
