Hi,
I just start using Copilot Studio recently and is learning how to create a bot, but in publish process I get some trouble.
Currently I'm using Copilot Studio in free trail.
Firstly I publish my copilot.

After that I'm trying to publish to a demo website and soon get an error:
Object not found.
Diagnostic Trace Id: Trace id not available. Headers: {"cache-control":"no-cache, no-store",...

Then I try the other channel: "Custom website", I copy the HTML embed code and add the code in my localhost webpage, but the bot is not available and returns 404 Not Found error.

What's the reason my bot can't be published on those channels? I'm not sure if the reason is authentication - as the document "Key concepts - Publish your bot" (https://learn.microsoft.com/en-us/microsoft-copilot-studio/publication-fundamentals-publish-channels) says:
"If you want to allow anyone to chat with your bot, select No authentication authentication."
"If you want to use other channels and still have authentication for your bot, select Manual authentication."
but the other problem is, I can't reach the authentication page.

So how can I publish my bot to the Demo website or Custom website? Or I can't do this with free trial? Thanks.
