Answer
Navigate to the target Aurena page and search/filter it the way you want the link to behave, then copy the resulting URL straight from the browser's address bar — that URL already reflects the page's correct identifier and filter syntax. Back in the Lobby link configuration, replace the fixed values in that copied URL with dynamic references to your data source's columns using the $[data_source_column] syntax — for example, a URL ending in a filter on an order number becomes ...eq $[ORDER_NO] to substitute in each row's actual order number dynamically.
