Select field, api options format

Hi everyone,

By reading the doc here: https://getkirby.com/docs/reference/panel/fields/select#options-via-api

The api endpoint should return an array

as shown above in the manual option setting

But there is no such array example.
Can someone shows me what should like a json response to fit the options, because my json array gives me an error :
