Update row in Google sheets problem

Hey
If I use 3 modules (Google sheets-GPT-google Sheets) and GPT pulls text from A2 cell in the first module, what module do I need to pick (and how to set it up) for GPT output that should update cell B2?
And do the same every time new row (new data in column A: A3, A4 and so on) is added (resulting in output going to B3, B4 and so on)?
Thank you
