Issue with Twill Browser Component Not Loading Existing Many-to-Many Relationships

[rnr1721]

I'm having an issue with the Twill Browser component not loading existing relationships when editing a record. The browser field appears correctly, but it's always empty even when there are existing relationships in the database.

My Setup:

• I have a User model that has a many-to-many relationship with Animal through a pivot table user_animal_teams
• The pivot table has additional fields such as team_code, is_primary_owner, position, etc.
• The relationship is defined correctly and works in other contexts outside the Twill admin

What I've Tried:

• Configured the repository with protected $browsers = ['animals'];
• Tried implementing custom getFormFieldsForBrowser() method
• Checked that the relationship returns data by adding logging in the repository
• Confirmed that IDs exist in the database through manual queries

// User model
public function animals(): BelongsToMany
{
    return $this->belongsToMany(Animal::class, 'user_animal_teams', 'account_id', 'animal_id')
        ->withPivot('team_code', 'is_primary_owner', 'trainer_id', 'position');
}

// Repository
protected $browsers = ['animals'];

// Form
$form->add(
    Browser::make()
        ->name('animals')
        ->label('Animals')
        ->modules([Animal::class])
);

Also try this (in repository)

    public function getFormFields($object): array
    {
        $fields = parent::getFormFields($object);
        $fields['browsers']['animals'] = $this->getFormFieldsForBrowser($object, 'animals', null, 'name', 'animals');
        return $fields;
    }

When I log $object->animals, I can see the related animals exist. But when the form renders, the browser field is always empty.
How can I get the Browser component to properly load and display the existing relationships?
