Can’t find anywhere in the docs do this. If it’s not possible. how to update with API are there any examples I can use with axios?

Also when I use a axios get I am able to see my custom field returned.
axios.get(${oktaURL}/api/v1/users/${id})

But with the nodejs API client Custom fields do not appear
client.getUser(‘id’)
.then(user => {
console.log(user);
});
