What device information or headers are included in authentication when using AllowSingleSignOnUsingOSPrimaryAccount in WebView2?

[GebreegziabherGebru]

What new information (headers or claims) is actually included in the authentication flow after setting AllowSingleSignOnUsingOSPrimaryAccount = true in a WebView2 control?

From the docs, it seems this flag only enables implicit sign-in using the OS account. But does it cause Azure AD to receive device-related metadata (e.g., device ID, compliance state) that would allow Conditional Access policies requiring device context to succeed? Or is the behavior strictly limited to silent SSO without adding device claims?

We’re trying to determine whether enabling this flag is enough to satisfy Conditional Access device-based policies, or whether additional configuration is required.
