Custom Backed Enum cast

[CristianGiordano]

Is it possible to create a custom backed enum cast?

I have an incoming webhook payload as :

{
    // ....
   "type": "Account", // "Contact" | "Lead" etc
}

My enum:

enum WebhookType: string
{
    case Account = 'account';
    case Contact = 'contact';
    case Lead = 'lead';
}

I tried extending the EnumCast however I think due to the nature of native enums, my #[WithCast(ToLowercaseEnumCast)] isn't triggered on my data class.

class ToLowercaseEnumCast extends EnumCast
{
    public function __construct(
        protected ?string $type = null
    ) {
        parent::__construct(gettype($type) === 'string' ? strtolower($type) : $type);
    }
}

Is this possible at all? I can just use the same casing from the webhook, but I wanted consistency in my app.
