Custom datetime filter within relation

I am building a table for an Alert model, whose timestamp is found through a 'timestamp' column from a related model (event), and I'm trying to get a filter on that, like this:

Filter::make('event.timestamp')
  ->form([
      DateTimePicker::make('event.time_from')
          ->seconds(false),
      DateTimePicker::make('event.time_until')
          ->seconds(false),
  ])
  ->query(function (Builder $query, array $data): Builder {
      return $query
          ->when(
              $data['time_from'],
              fn (Builder $query, $date): Builder => $query->whereDate('timestamp', '>=', $date),
          )
          ->when(
              $data['time_until'],
              fn (Builder $query, $date): Builder => $query->whereDate('timestamp', '<=', $date),
          );
  })



However, I get an error pointing 'time_from' and 'time_until' indexes do not exist in $data, which seems correct since $data is completely empty.

What I'm missing in between? Why is $data empty?
Solution
Okey, I just solved it easily by using whereHas on QueryBuilder
                Filter::make('timestamp')
                    ->form([
                        DateTimePicker::make('time_from')
                            ->seconds(false),
                        DateTimePicker::make('time_until')
                            ->seconds(false),
                    ])
                    ->query(function (Builder $query, array $data): Builder {
                        return $query
                            ->when(
                                $data['time_from'],
                                fn(Builder $query, $date): Builder => $query->whereHas('event', function ($event) use ($date) {
                                    $event->whereDate('timestamp', '>=', $date);
                                }),
                            )
                            ->when(
                                $data['time_until'],
                                fn(Builder $query, $date): Builder => $query->whereHas('event', function ($event) use ($date) {
                                    $event->whereDate('timestamp', '<=', $date);
                                }),
                            );
                    })


Although I feel like there should be (or there actually is) a better way to do this
