Hi there. I'm trying to parse the raw transaction. I have example in_msg:

"in_msg": {
"@type": "raw.message",
"source": "EQBK05ruPpEltNYZE4bpUOG_JyuYYpG6Ro54wn6a7emgnYT7",
"destination": "EQARULUYsmJq1RiZ-YiH-IJLcAZUVkVff-KBPwEmmaQGH6aC",
"value": "600235000000",
"fwd_fee": "1321344",
"ihr_fee": "0",
"created_lt": "44028120000002",
"body_hash": "D//8Zajek+sk2k3tq88z50cE1OIgalO92btHO81rBSU=",
"msg_data": {
"@type": "msg.dataRaw",
"body": "te6cckEBAgEAZwABbw+KfqUABeSQPenMGFi7LJcACADvO5kConGyoByJOKUjz+JOcYR6rramIAAe1Ep3rA5wnBA4B0MDAQBT/Pnlj4AGAnpo0IBn5ZHP4Zot3in354PWuSUFZoFsZNpUF0d1VMlhsqkPMulYwQ==",
"init_state": ""
},
"message": "D4p+pQAF5JA96cwYWLsslwAIAO87mQKicbKgHIk4pSPP4k5xhHqutqYgAB7USnesDnCcEDgHQwI=\n"
}

I'm trying to figure out how to decode message field but cannot find any info in docs. Simple base64 decode is not working.
