Hello,
Before you enable the "Hide desktop icons" policy from GPO, try creating a desktop shortcut for the two selected desktop icons via GPP:
User Configuration –> Preferences -> Windows Settings -> Shortcuts.
Here's a detailed guide:
Create Desktop Shortcuts on Domain Computers via GPO | Windows OS Hub
The GPO at the top of the list has the highest precedence and will be applied last, its settings will override any conflicting settings from GPOs lower in the list. See reference: Group Policy Processing Order (GPO Hierarchy) - Active Directory Pro

I hope this information helps.
Best regards,
