Waiting for Mapped Object

We have this object in our script:



wSelProduct :=  Aliases.Sys.Prophet.WaitWindow('TfrmDualSelItems', 'Import Products',-1,10000);



I have created a new mapping for this object but I'm not sure how to use this with 'WaitWindow' or something similar.



I could do



wSelProduct := Aliases.Sys.Prophet.ImportProductsDualSelItems;



but what I want is to add in a bit of waiting time for the object.
