TextColumn relationship unique values

I have a text column that contains country names through a relationship. How do I get this to only display unique names?

Tables\Columns\TextColumn::make('countries.name'),

Tables\Columns\TextColumn::make('countries.name'),

I am not sure I follow? If it is a relationship it will show what's in the relationship. The countries should only have unique names within it?

To clarify, countries is a has many through (cities) relationship. So if a title has two USA cities, USA is showing up twice in the countries column.

I do it like this, but probably it's not the "correct" way, though it works

->state(
    fn($record) => $record->countries->map(fn($country) => $country->name)->unique()
)

->state(
    fn($record) => $record->countries->map(fn($country) => $country->name)->unique()
)
