Datasource for LengthAwarePaginator

[fooino]

the datasource method output type can be eloquent or query builder
or we can define a collection
but what about pagination?

    public function datasource(): Collection
    {
        return app(GetPaginatedCountriesAction::class)->run();
    }

the GetPaginatedCountriesAction is a class in vendor and I do not access to the content of class

the class content is like this

class GetPaginatedCountriesAction
{
    public function run(
        array|string $select = ['*'],
        array|string $with = [],
        array|string $withCount = []
    ) {
        return Country::disablePrioritiable()
            ->sortByStatus()
            ->select($select)
            ->continentId(ef('continent_id'))
            ->search(ef('search'))
            ->status(ef('status'))
            ->with($with)
            ->withCount($withCount)
            ->paginate(pg())
            ->appends(request()->all());
    }
}

it returns paginated countries list but the powergrid throws exception

datasource(): Return value must be of type Illuminate\Database\Eloquent\Collection, Illuminate\Pagination\LengthAwarePaginator
