Use of AllowSingleSignOnUsingOSPrimaryAccount

[LK-Global]

I was wondering about the use of AllowSingleSignOnUsingOSPrimaryAccount with the creation of the CoreWebView2Environment...
https://learn.microsoft.com/en-us/microsoft-edge/webview2/reference/winrt/microsoft_web_webview2_core/corewebview2environmentoptions?view=webview2-winrt-1.0.1774.30#allowsinglesignonusingosprimaryaccount

We have a client who is failing a SAML login that requires using an AD user Id and authentication which this seems to address. BUT => We do not have this environment and have no way of testing.

Is there any broader documentation that can help understand what this parameter is intended? Also, it appears that setting this parameter to true has no impact on operation in other environments. Can anyone validate what setting this to true when creating CoreWebView2Environment in a non AD authentication environment does?
Let me know if you need more details or have any questions.
Thanks.
