[SalesForce] Query From Shared Data Extension

I have a shared Data Extensions across multiple Business Units.

I need to run a query from it in a Child BU but every time I try to run I get

"× An error occurred while checking the query syntax. Errors: Leads is
not a known data extension or system data view. You can only query
existing data extensions or system data views."

Is there a special prefix I need to add in the FROM portion of the Query?

Query is:

SELECT...
FROM Leads
WHERE...
