Change nested arrays into one array


I have a situation like below:


I have array "Allowance_Plan’ and in this array I could have many elements which also are arrays.
Child arrays as a elements contains objects.

In this case I have 2 arrays with 2 object in each of them.

As a final result I would like to receive one array “Allowance_Plan” which contains 4 objects. (2 from first child array and 2 from second child array)
Please suggest how to solve this problem.

Here’s an example pipeline:
