[G-Sheet] how to have the same action thant watch rows with a webhook

Hi I have a scenario triggered by a wtch row G-sheet module.
The aim is to run the scenario with the last added rows that have not been processed yet.

The thing is I don’t need it to run every 5 minutes. my process is not even daily, but sometimes, I will do it 5-10 times a day.
So I think the best way is to trigger it with a webhook. but I would like to keep it the wat it is, and that the webhook just play the scenario as if it were the run once button… Do you know if it is possible?

Yes, this is possible with Google script. We have done it for many clients.
You can write a script in Google sheet to trigger the webhook based on your condition.
