Is it actually a property of an enum or rather one of the enum literals?

If it is actually a property, you will need to obtain an instance of the FrontendScreen enum first. If PLAYGROUND is actually an enum literal and you want to bind this literal to a variable, use:

$screen: FrontendScreen( this == FrontendScreen.PLAYGROUND )
