AAD Seamless Single Sign-On and Chrome

For anyone trying to resolve this, after my research this is the exact requirements (Chome-side, your Azure AD setup has its own stuff) I needed:

Latest "Chrome Enterprise Policy List": https://support.google.com/chrome/a/answer/187202?hl=en

GPO Settings
User Configuration\Policies\Administrative Templates\Google\Google Chrome\HTTP Authentication
-Kerberos delegation server whitelist
autologon.microsoftazuread-sso.com,aadg.windows.net.nsatc.net
-Authentication server Whitelist
autologon.microsoftazuread-sso.com,aadg.windows.net.nsatc.net
# Needed if you're blocking extensions from being installed to whitelist this one
User Configuration\Policies\Administrative Templates\Google\Google Chrome\Extensions
-Configure the list of force-installed apps and extensions (Enabled)
ppnbnpeolgkicgegkbkbjmhlideopiji
-Configure extension installation allow list (Enabled)
ppnbnpeolgkicgegkbkbjmhlideopiji

Note: That extension ID I pulled from https://chrome.google.com/webstore/detail/windows-accounts/ppnbnpeolgkicgegkbkbjmhlideopiji (Windows Accounts)
