 - The `CopilotEmbeddedChatHosts` container type setting is now required to use [SharePoint Embedded agent](./development/declarative-agent/spe-da-adv.md#csp-policies). It must be set by the application owner via [`Set-SPOContainerTypeConfiguration`](/powershell/module/sharepoint-online/set-spocontainertypeconfiguration) and can optionally be overridden by consuming tenant administrators via [`Set-SPOApplication`](/powershell/module/SharePoint-online/set-spoapplication).
