• When you generate a table, you can click on the data and a menu will appear in the add-on. If you click on “show params”, the query sheet will open in a new tab, as you can see in the GIF above.
• If you open the hidden sheet “DataslayerQueries”, which is generated automatically. If you don’t know how to open hidden sheets, you can click here for more information.
