Relation manager try to get relation with camel case | Filament | Page 1

Empty relation manager, with only:

class DomainsRelationManager extends RelationManager
{
    protected static string $relationship = 'domains';

    public function form(Form $form): Form
    {
        return $form
            ->schema([
                Forms\Components\TextInput::make('id')
                    ->required()
                    ->maxLength(255),
            ]);
    }

    public function table(Table $table): Table
    {
        return $table
            ->recordTitleAttribute('id')
            ->columns([
                Tables\Columns\TextColumn::make('domain'),
            ])
            ->filters([
                //
            ])
            ->headerActions([
                Tables\Actions\AttachAction::make(),
            ])
            ->actions([
                Tables\Actions\DetachAction::make(),
            ])
            ->bulkActions([
                Tables\Actions\BulkActionGroup::make([
                    Tables\Actions\DetachBulkAction::make(),
                ]),
            ]);
    }
}

When I try to attach, I get the error: Call to undefined method App\Models\Domain::gamesTypes()

I have App\Models\Domain::games_types(), and it works on every relationship, but not in relation managers (tries several models)

Is this a bug?
