It's been a while since I have dived into Salesforce's Flow product and before the Flow Lightning UI refresh rolled out.
I have done this in the Flash based UI so I am puzzled but what I am doing wrong now.
Use-case: A user is prompted to associate an existing record in Salesforce to another by creating a junction object.
Problem: I am getting stuck on the part after the user inputs a keyword which then drives a contains Lookup tool. The Lookup tool stores a single record to a variable– however, how can I display this variable as a choice selection in a screen for the Flow end-user to decision on?

The Get Records element in the new Flow Builder parallels the old Fast Lookup, and it comes with an option to support selecting more than one record to a Record Collection variable.
To configure that choice, double-click on the Get Records element to open its Edit screen. Then, find the section shown below:
Select, as shown here, "All Records", and name an sObject collection variable, to store all of the records matching the query that you specify.
