To set up user management, follow these steps:

1. Create an API endpoint on the "App users" (WebUser) data structure with a condition like "role like admin" on the user's session
2. Create a new web page with a security condition where "role == admin"
3. Add a Table component to that page.

## Step 3.2: Configure Upvoting

Let's add two new fields to `Features` data structure:

1. **Upvotes ("**&#x4E;umber")
2. **Users Upvoted IDs ("**&#x41;rrayLink → WebUser").

Next, create a new page for upvoting, which should be accessible to all authorized users:

Note that we've added the "Upvotes" field as a counter on the cards.

Now, we configure actions:

* Add a new data structure `upvotes` with the following fields:
  * `user_id`, type of `link→WebUser`
  * `feature_id`, type of `link→Features`
* Create an API endpoint for adding objects to `upvotes`
* Design a scenario for counting votes (avoiding duplication).

Finally, we are sorting the cards by `upvotes`.
