How do you add processing spinner to wizard button?

Wizard::make($steps)
                    ->submitAction(new HtmlString(Blade::render(
                        <<<'BLADE'
                    <x-filament::button
                        type="submit"
                        size="xl"
                        color="primary"
                    >

                        {{trans('Start Questionnaire')}}
                    </x-filament::button>
                    BLADE
                    )))
                    ->nextAction(
                        fn (Action $action) => $action->color('primary'),
                    )
