Enable the use of private models in example scripts using use_auth_token
# 🚀 Feature request

Currently private models can be used with the examples scripts by setting the `use_auth_token argument` as `True` however this doesn't seem to be an option for private datasets.

## Motivation

Enabling the use of private datasets using the example scripts

## Your contribution

I'm happy to work on a PR to add this to all example scripts if this is indeed the case and I haven't missed another method for using private datasets.
