Since it’ll be very hard for you to replicate how the rows are structured I’d recommend just triggering the “add row” button with JS thus letting ACF do the creation.
//Delay a function a few hundred millseconds to give ACF time to create the row then do your own insertion. Preferably via function call
Thanks for your help.
That is what I had in mind and I did look at “acf-pro-input.js” trying to understand how to trigger the click.
I’ve tried this in the console for a quick test but no rows are added
