"Remove item from colleciton" collection operation does not currently support to store the removed item to a variable, because of this, we will need to use two collection operations to achieve the goal of removing an item from collection + store the removed item to a variable.
1. Get item from collection
2. Remove item from collection
If the "Remove item from collection" has the "Store Item" field, that can avoid by just calling the "Remove item from collection" without the "Get item from collection" first.
