Hi Andres,
A couple of days ago we released a new version of the dandelion add-on for Google spreadsheet; in this new version you don't need a dandelion account to start working with dataTXT, our named-entity extraction tool. Unfortunately, in the rush of deploying the new add-on, we didn't have time to update the "getting started" guide available on our website. This is why the documentation says to enter your API codes in the "Configure" tab, but you can't find it in the menu.
Please, skip that step and keep on with the guide, you will be able to annotate texts without having to insert your API codes.
Let us know how it goes,
All the best
