After subscription purchase, We plan to do JWS signature validation on the server-side instead of decoding the JWS in the IOS app. Currently, after purchase, I am getting the decoded details instead of the JWS in response. Could you please let me know which methods give the JWS after the subscription purchase inside the IOS app? Method's I am calling the inside the APP Product.purchase() ->given the purchase result. After purchase, we get the transaction object as a response Transaction.finish() //concluding the transaction Fetch the purchase information of the product transaction.currentEntitlement Sample response after the purchase was made. But we required the JWS instead of the below-decoded data. ({  "header" : {   "alg" : "ES256",   "x5c" : [    "**********",    "***********",    "*****************"   ]  },  "payload" : {   "bundleId" : "com.*******",   "deviceVerification" : "",   "deviceVerificationNonce" : "",   "expiresDate" : 1640100970000,   "inAppOwnershipType" : "PURCHASED",   "originalPurchaseDate" : 1631601452000,   "originalTransactionId" : "1000000877135811",   "productId" : "com.e**********",   "purchaseDate" : 1640100670000,   "quantity" : 1,   "signedDate" : 1640100987198,   "subscriptionGroupIdentifier" : "*****",   "transactionId" : "1000000935313340",   "type" : "Auto-Renewable Subscription",   "webOrderLineItemId" : "************"  },  "signature" : "64 bytes (verified)" })
