What should you configure to apply GPO settings to the users when they sign in to the session hosts?

Your network contains an on-premises Active Directory domain and a Windows Virtual Desktop deployment.

The computer accounts for all the session hosts are in an organizational unit (OU) named WVDHostsOU. All user accounts are in an OU named CorpUsers.

A domain administrator creates a Group Policy Object (GPO) named Policy1 that only contains user settings.

The administrator links Policy1 to WVDHostsOU.

You discover that when users sign in to the session hosts, none of the settings from Policy1 are applied.
