Automate creating an item on another board and inserting the original item link

I have two boards, one is internal and the other external to our organization. I have automation set up where if certain conditions are met on an internal item, a matching item is created on the external board.

That part I have down, but what I want to know is can I get the item link of the original internal item, then insert that link into a specific column in the external board. The idea is that we’ll have this column for our internal team to be able to easily find the original item.

Hope that makes sense and thanks for your time!
