how to show active product dimensions through lookup in custom form (InventProductDimensionLookup form)

Hello, friends

I need to show active product dimensions through lookup. In a standard way, for exampe, InventJournalMovement form its done through InventProductDimensionLookup lookup form(please see screenshot attached). I need to implement similar lookup in my own custom form. Have you done that before? Can you provide some information on how to achieve this. It would be nice if you could help me in this.

Best regards,

Roberts
