Cyclic data retrieval from google table row by row

What are you trying to achieve?

Hi. I’m sure the question is very simple and stupid, I’m just missing some little thing. Please help)))

I have a task to set a loop on a process.
The process is as follows.
1 Google Table (take the 1st row from it, Column A - by default)
2 GPT chat writes on the question from line 1
3 Update column 3 in row 1
Then I realize that I need to put a Repeater between Google Table (Process 1 - aka Trigger) and GPT Chat (Process2).
I need to specify the number of cycles, depending on how many rows of queries I want to process.
The problem is that when the Repeater is triggered, each time only row 1 is taken into account, and data is written to it N times.
How to make google table take data as many times as there are rows in the table?
