## Explanation

This Flow takes in two inputs: the **First List** (String list) and **Second List** (String list). Then, create the Matched String List (String list) using the create data step. The first list is passed for each step which loops through the list. Then the list is compared to the second list using the "**String is in List"** step if the strings match, they are then passed to the **"Add Items to List"** step, which creates the list of matching strings from the two lists.
