Can you please try with “selectable objects” option.
Have a look at this https://docs.mendix.com/refguide7/reference-selector/#constrained-by.
This will explain to you how to constrain reference selector data with other data on the page.
If you don’t get this just have a microflow in the selectable object of reference selector and get the required data.
It should trigger. Please Check for reference selector’s microflow access for current user.
