How to use OAEP encrypt data with this public key

Question

I am re-writing a Java application with NodeJS. I need to encrypt a message using these parameters but I cannot get it work.

{
    "oaepHashAlgo": "SHA256",
    "pubKeyIndex": "0004",
    "Sid": "0001nEDMjbDVqwgpjLTOKNr5_2z63SykIz2PNsKqDqEzlORG051o8drUp_8OwgXusTGzCSTlrmJMqkolMHTzb00FjEKWdds",
    "random": "586AADD845626E05A154DD2517F0C9B0",
    "pubKey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
}

From these parameters I guess I will need to do RSA-Oaep encryption. As you can see the first half of pubKey is likely to be an HEX code. so I turn it to buffer but still no clue what format it is.

const buff = parseHexString('82ADCD6B111C6659B51D11E833F3B4C5...'))
// => <Buffer 82 AD CD 6B 11 1C 66 59 B5 1D 11 E8 33 F3 B4 C5...

crypto.publicEncrypt({
  key: buff,
  oaepHash: oaepHashAlgo,
}, Buffer.from("MyDataHere"))

// => Error: error:0909006C:PEM routines:get_name:no start line 

As expected, I got error for not passing a valid pem file.

So, What is format of this public key? and how do I use it?
