Translation in process step

Hello everyone,

Does anymore know how to translate text in a process step ?

We are updating a pwo reason text with some data and some of them are translated key to be translate when we do the update on the pwo.

I've tried basic string but I guess we have to use a method for that following the culture defined on the user who request ?

Value = "#LDS#External" + $OrderReason:Text$

Thanks for your help !
