hasMany Model don't work

$LastWeek = DB::table('group')
                                     ->where('group.region','=',$regionName)
                                     ->whereBetween('date',[$date1, $date2])
                                     ->join('sale_number', 'group.sales_person_id', '=', 'sale_number.id')
                                     ->selectRaw("sale_number.id,SUM(number) as sum_prev_week")
                                     ->groupBy('sale_number.id')
->get();

group table region, sales_person_id

sale_number table id, date number

Now I am using the above query work fine. I am trying to use Laravel hasMany model.

class Group extends Model
{
    use HasFactory;

    public function sale_number()
    {
        return $this->hasMany(SaleNumber::class,'id','sales_person_id');
    }

$lastWeek = Group::where('group.region','=',$regionName)
                                    ->with('sale_number')
                                    ->selectRaw("sale_number.channel,SUM(number) as sum_prev_week")
                                    ->groupBy('sale_number.id')
                                    ->get();

SQLSTATE[42S22]: Column not found: 1054 Unknown column 'sale_number.id' in 'field list'

SELECT
  sale_number.id,
  SUM(number) AS sum_prev_week
FROM
  `group`
WHERE
  `group`.`region` = Midwest
GROUP BY
  `sale_number`.`id`
