How to sort the dropdown in a list filter

I have 2 models: Property and Country. Each Property belongs to a country.

public $belongsTo = [
        'country' => [
            \Jlh\Property\Models\Country::class,
            'order' => 'name asc'
        ],
];

On the Property backend list, I have a filter for Country but I can’t get the countries to list in alpha order:

scopes:
  country:
      label: Country
      modelClass: Jlh\Property\Models\Country
      conditions: country_id in (:value)
      nameFrom: name

Any help is appreciated.
