Convert objectGuid to UUID string using Javascript - active-directory

Question

I have been looking for a way to convert the ObjectGuid out of Active Directory is a special type that gets converted to a string, which is odd looking, using libraries such as ldapjs and or adding it as a claim using ping federate. An example of this is the following:
const ldapjs = require("ldapjs");
let _client = ldapjs.createClient({
"url": this._ldap_uri
});
_client.search(this._search_dn, opts, (error, res) => {
res.on("searchEntry", (entry) => {
console.log(entry.object.objectGUID)
}
Here is an example of the output that comes out of ldapjs. The same comes out of a ping federate when you add it as a claim.

However, this is equivalent to a valid UUID.
b9****48-6***-42**-a**f-2d5f*****40b
What I am trying to do is convert this strange value to a the correct UUID. I have scoured and tested a few different postings and websites but I have not found a valid solution.
Here are a few I researched:
Read objectGUID from active directory
Javascript convert GUID in string format into Base64

If anyone has a solution to this it would be appreciated.

experiment with this code (read GUID) :
String.prototype.padLeft = function( len, str ) {
//return Array( len - String(this).length + 1 ).join(str) + this;
var s = this;
str = str || '0';
if ( str.length > 0 ) {
while ( s.length < len ) {
s = ( str + s );
};
}
return s;
}
var destAD = GetObject("LDAP://dc.yourdomain.pl/cn=Administrator,cn=Users,dc=yourdomain,dc=pl");
var guidValueArr = destAD.Get("objectguid").toArray();
var guid = "", i;
for ( i = 0; i < guidValueArr.length; i ++ ) {
guid += guidValueArr[i].toString(16).padLeft(2,"0");
}
var guidFormated = guid.replace(/(.{2})(.{2})(.{2})(.{2})(.{2})(.{2})(.{2})(.{2})(.{4})(.{12})/, "$4$3$2$1-$6$5-$8$7-$9-$10");
alert( guidFormated );
Universally unique identifier
