Lets say you have a list collector variable on the catalog item and you want to get display value of the values selected in that field.
Here is how i did it
created a flow variable , for example 'Resolution Details' and click on script option and use below code in the script area
var t = 'table name where you are storing your list collector value';
var l = fd_data._21__get_catalog_variables.resolution_details.toString();
var dv = new getLCDisplayValues().getValues(t,l);
return dv;
set flow variables as shown below
