How to populate multi select list with default selected values

I have this multiple select form field where I load the options and try to set the default values:

Forms\Components\Select::make('platforms')
    ->options(function () {
        return Platform::query()
            ->get()
            ->mapWithKeys(fn ($platform) => [$platform->id => $platform->name]);
    })
    ->label(__('Platforms'))
    ->default(function () {
        return ChannelPlatformFrequency::query()
        ->where('channel_id', request()->route('record'))
        ->get()
        ->mapWithKeys(fn ($channelPlatformFrequency) => [$channelPlatformFrequency->platform_id => $channelPlatformFrequency->platform->name]);
    })
    ->multiple()
    ->required(),

Forms\Components\Select::make('platforms')
    ->options(function () {
        return Platform::query()
            ->get()
            ->mapWithKeys(fn ($platform) => [$platform->id => $platform->name]);
    })
    ->label(__('Platforms'))
    ->default(function () {
        return ChannelPlatformFrequency::query()
        ->where('channel_id', request()->route('record'))
        ->get()
        ->mapWithKeys(fn ($channelPlatformFrequency) => [$channelPlatformFrequency->platform_id => $channelPlatformFrequency->platform->name]);
    })
    ->multiple()
    ->required(),

The default method does not seem to work. It does not show any selected options. As far as I know I should use the default option to set the default selected values. As you can see in the image I attached the available options (up) and the default values (down) should match.

Is this on Edit or Create? default() is for Create only

On the edit page Hmmm ok, which one should I use on the edit page?

Since your model already was saved there is no default anymore. You can use mutateDataBeforeFill to fill the form with default data

Will try that! Thanks

https://filamentphp.com/docs/3.x/actions/prebuilt-actions/edit#customizing-data-before-filling-the-form Is this the documentation about the method you mentioned? I tried to do so using this code, but it seems like mutateRecordDataUsing is not triggered:

  public static function table(Table $table): Table
    {
        return $table
            ->columns([
                Tables\Columns\TextColumn::make('name')
                    ->label(__('Name'))
                    ->sortable()
                    ->searchable(),
                Tables\Columns\TextColumn::make('created_at')
                    ->label(__('Created at'))
                    ->dateTime()
                    ->sortable()
                    ->toggleable(isToggledHiddenByDefault: true),
