Pivot not saving to db?

                                Forms\Components\Select::make('owningCompanies')
                                    ->label('Owning Company')
                                    ->relationship('owningCompanies', 'name')
                                    ->options(fn() => Company::select('name', 'id')->where('type', 'OWNING')->get()->pluck('name', 'id'))
                                    ->preload()
                                    ->multiple()
                                    ->maxItems(1)
                                    ->columnSpan(3),

    public function owningCompanies(): \Illuminate\Database\Eloquent\Relations\belongsToMany
    {
        return $this->belongsToMany(Company::class)->where('type', 'OWNING');
    }
