show but not modify a field

how can i display but not modify some fields such as the api_token field in User ?

I have the User resource like this:

public function fields(Request $request)
{
    return [
        ID::make()->sortable(),

        Gravatar::make()->maxWidth(50),

        Text::make('Name')
            ->sortable()
            ->rules('required', 'max:255'),

        Text::make('Email')
            ->sortable()
            ->rules('required', 'email', 'max:254')
            ->creationRules('unique:users,email')
            ->updateRules('unique:users,email,{{resourceId}}'),

        Password::make('Password')
            ->onlyOnForms()
            ->creationRules('required', 'string', 'min:8')
            ->updateRules('nullable', 'string', 'min:8'),
        Text::make('Api_token'),

        BelongsToMany::make('Languages'),

    ];

}

I would like the Api Token field not to be editable, how could I do?
