this is the code how a PurchaseTransaction is created. Now write me a code to create a New Transaction from a PurchaseTransaction with json_decode when necessary as well as call Merchant, User, Agent where necessary.
// Assuming $purchase_trx is the created PurchaseTransaction instance

// Decode parameters and request if needed
$trxParams = json_decode($purchase_trx->parameters, true);
$reqParams = json_decode($purchase_trx->request, true);

// Fetch related models
$user = \App\Models\User::find($reqParams['user_id'] ?? null);
$agent = isset($reqParams['agent_id']) ? \App\Models\Agent::find($reqParams['agent_id']) : null;
$merchant = isset($reqParams['merchant_id']) ? \App\Models\Merchant::find($reqParams['merchant_id']) : null;
$product = \App\Models\Product::find($reqParams['product_id'] ?? null);

// Prepare data for New Transaction (all $fillable fields)
