G Suite - Activity Read Range

How can I read a range with Google Suite Activities without knowing how many columns my datatable will have.

The documentation of Read Range in GSuite Activities says we can put only the first cell of the table, but it only reads the cell value instead of the whole table.

Hello @Pedro_Pais I would like to help you. Basically if you want the whole table you need to leave that field empty

Try it and let me know any concern
