Co-pilot for External User

Hello,

I used the Co-Pilot on my SharePoint site through SPFx, and I shared that site with an external user. I also shared the Co-Pilot with that external user, but they are unable to search for information on the SharePoint site. An error message states, 'LPC is not enabled for guest users.'

"{"error":{"message":"Unauthorized","code":"PermissionDenied"}}"

Can external users use the Co-Pilot, and is there any solution for this?

Thank You
