[HANDS-ON BUG] Bonus unit 1 - Not able to Push the Model

# Describe the bug

I have been able to train the model. Generated new token as well. When I clicked login to enter the new token, It generated a ''8 digit code'' and asked to **Verify and authenticate** the code. When done, I could not enter the new token generated as there was no pop up box when login.

I further executed the command. It executed but finally displayed the following error:

"ConnectionError: Network error: Request error: HTTP status client error (403 Forbidden), domain: https://huggingface.co/api/models/ThomasSimonini/ppo-Huggy/xet-write-token/main"

# Material
- Did you use Google Colab?
yes
If not:
- Your Operating system (OS)
- Version of your OS

Start by reproducing the login and flow in Google Colab, checking where the generated token is expected to be entered and what permissions the Hugging Face model repository allows. Done means the token can be supplied during login and the model push completes without the reported 403 error.
