Google colab and API token access

Hello!

I am trying to obtain the building polygons and locations using the google colab notebooks.
First, I requested access to Microsoft to be able to use Jupyter notebook and test the "Vatican city" example and it worked. Then I used the same code on google colab, and I got an error. To make sure, that this is not due to versions, I used printed all the packages versions on the Microsoft jupyter hub and installed them on my google colab.
However, I keep getting the same error.

The error I get is the following:

Code:

catalog = pystac_client.Client.open(
"https://planetarycomputer.microsoft.com/api/stac/v1"
)
items = catalog.search(
collections=["ms-buildings"], query={"msbuildings:region": {"eq": "Vatican City"}}
)
item = next(items.get_items())
item

collection = catalog.get_collection("ms-buildings")

asset = planetary_computer.sign(item.assets["data"])

df = geopandas.read_parquet(
asset.href, storage_options=asset.extra_fields["table:storage_options"]
)
df.head()

I am guessing the error, its the API token? but I think I am following the steps in the Microsoft API documentation for the datasets.
What am I doing wrong?

Thank you !

The reported entry point is the Google Colab notebook code using pystac_client.Client.open, planetary_computer.sign, and geopandas.read_parquet; first reproduce it in Colab and capture the full traceback and package versions rather than relying on the linked screenshot. Done means identifying the authentication or environment difference and documenting a verified way to retrieve the ms-buildings asset.
