In your case, the relation is a 1-1 relationship. As a consequence you can drag and drop a field, and not a relationship.
You should have a field named “authUser” or “accountingWallet” (depending on the collection you are configuring), you can drag and drop it into the summary view to display a link to the related element in your view.
If you want to customize the information that will be displayed in this field (instead of the id), you can:
- Click on “Edit Layout”
- Select the gear icon next to the name of the collection for which you want to display something else than the id
- Select a “Reference field” (this field will be displayed instead of the id)
