If I call Invoke of chain code, I get transaction ID in REST response. e.g.
{
  "jsonrpc": "2.0",
  "result": {
    "status": "OK",
    "message": "e00848bc-71c3-422f-b637-cbfc9d2e2042"
  },
  "id": 4
}
How can I access this transaction ID (e00848bc-71c3-422f-b637-cbfc9d2e2042 in above example) programatically in my invoke function of chaincode?
