Google Sheets integration

Hi, after my trigger, I'm doing a search for an email address, using the row number I want to update a cell by including the new value and not replace it. eg.

I did this but it just added to the next column

Just checked your workflow and it seems you are missing to pass values in double quotes.

You need to pass comma-separated values within double quotes as "product1","Product2".

Please correct your mapping in the Update Row action step.
