Additional validations on the `action` method for Standalone action

When using a standalone action, is it possible to do additional form validations inside the action() method. The reason why I need to do this is because some of the validations are based on the argument passed to the Action (https://filamentphp.com/docs/3.x/actions/adding-an-action-to-a-livewire-component#passing-action-arguments) on the blade file.

because the arguments are not available inside the rules() method of the component basically want to do the following based on the blade code below 
function addToCart(): Action{
  return Action::make('addToCart')
  ->form([
    //All the schema fields go here with validations
  ])->action(function($data, $arguments){
    //Do additional validations based on the value received from the arguments
     if($this->isAlreadyInTheCart($arguments['product_id'])) {
         //show an error message on the form
     }
  })
}
function addToCart(): Action{
  return Action::make('addToCart')
  ->form([
    //All the schema fields go here with validations
  ])->action(function($data, $arguments){
    //Do additional validations based on the value received from the arguments
     if($this->isAlreadyInTheCart($arguments['product_id'])) {
         //show an error message on the form
     }
  })
}
{{ ($this->addToCart)(['productId'=>$product->id])}}
{{ ($this->addToCart)(['productId'=>$product->id])}}

I've never tried in this context but I think you may be able to use Livewire's validate() with a set of custom rules: 
->action(function ($livewire) {
    $livewire->validate([
        // custom rules...
    ]);
})
->action(function ($livewire) {
    $livewire->validate([
        // custom rules...
    ]);
})

@Abishek you found a fix for this?

the validate() method worked, but I do show a small modal with the errors to be more intutive as the number of error messages on my UI is more.

Are you willing to share some code of it? I have a similar use case. I use the modal to upload an Excel file which I process with Maatwerk/Laravel-Excel I want to show the errors triggered by that import
