Is there an easy way to find out if the user has valid access with code?

Hi FluentCart Team,

I'm currently testing FluentCart before purchasing it and integrating it with Etch.

When a subscription is cancelled, attributes like expire_at return null, which makes it difficult to determine whether the user should still have access during the remaining billing period.

I temporarily used created_at, but this is not reliable for multi-year subscriptions or different billing cycles.

What is the correct way to programmatically detect if a cancelled subscription is still within its valid access period?

Thanks in advance.

add_filter('etch/dynamic_data/user', function($data, $user_id) {

    $customer = \FluentCart\App\Models\Customer::where('user_id', $user_id)->first();

    if (!$customer) {
        $data['subscriptions'] = [
            'has_subscription' => false,
            'has_valid_access' => false
        ];
        return $data;
    }

    $subscriptions = \FluentCart\App\Models\Subscription::where('customer_id', $customer->id)->get();

    if (!$subscriptions->count()) {
        $data['subscriptions'] = [
            'has_subscription' => false,
            'has_valid_access' => false
        ];
        return $data;
    }

    $active_subscription = \FluentCart\App\Models\Subscription::where('customer_id', $customer->id)
        ->where('status', 'active')
