I've signed up for the PowerUp challenge and have started the Autonomous agents course.
I was able to setup my own Dev environment and it took me to Power Apps home page with my own Dev environment selected automatically.
However, when trying to follow the steps provided in the resource file named "New Hire Onboarding Autonomous Agent Base Instructions.docx" file, I tried to go to copilostudio.preview.microsoft.com and it showed me a little box to select my Country and Get Started button.
I clicked on Get Started and then I was able to see the main Copilot Studio window. However, I only see the default Microsoft-PowerUp environment and Rose Okenwa Trial environment.
I'm not able to see my own Dev environment named "Prabhat Singh" as it's visible in make.powerapps.com.
Any idea how I can get access to my Dev environment in Copilot Studio as well?
