Making my own Account Payable process in Studio

I want to replicate account payable project on the studio. I wanted to know how it was made. How it does OCR of multiple files with different template and Also doing OCR in the Background. How to make such Task on Studio? I was not able to find any documentation. Please Help.

@aayush1997g There is no documentation on making sample processes, they were created to demonstrate how Control Tower works. But you can see the code of this step by double-clicking on it on Control Tower.
