TypeError: Cannot read properties of undefined (reading 'find')

Happens everytime I run the test code. Any ideas? Thanks.

[My Solution], I forgot to redeclare the axl class (check code below):
const axl = require("app-xbox-live");
var tokens="";
async function getUserToken(user, pass){
const token = await axl.Token(user, pass);
tokens = token;
};
async function getUserByXUID(GamerTag){
var amount = 15;
var xl = new axl.Account('XBL3.0 x=${tokens[1]};${tokens[0]}'); //this was my problem, needed to redeclare.
var GT = xl.people.find(GamerTag, amount).then(console.log);
console.log(GT);
};
getUserToken("username@email", "secretpassword");
getUserByXUID("GAMERTAG HERE");
