Accessing Tag EngUnit in Alarm Display Path Expression

Ignition
1

I try following the expression in the Alarm Display Path to get the tag Eng Unit metadata but the tag() function returns nothing:

{PathToParentFolder} +  " Critical Range "  + {value} + " " + tag({PathToTag} + ".EngUnit")

So how can we read the tag ".EngUnit" here?

Messed around with all kinds of properties and ended up with

tag(concat({itemPath},'.EngUnit'))

Using PathToParentFolder or FullItemPath ends up having 'default' doubled up in the tag path.
The tag diagnostics showed the path as

[default]default/Global/alarmTestTag

Why using simple + operand doesn't work here?
