AZ commands won't work if run within a docker container

I have successfully logged in to Azure by using OIDC:

```yaml
permissions:
contents: read
id-token: write

[...]

steps:
- name: Checkout code
uses: actions/checkout@v4

- name: Configure Azure credentials
uses: azure/login@v1.4.7
with:
client-id: #######
tenant-id: #######
subscription-id: #######
```

and AZ works fine after that step if I run them directly with azure/CLI@v1 or just by typing az commands.

however, if I create a basic github action that uses the docker container mcr.microsoft.com/azure-cli and I try to run commands right after the login, I get:

```shell
ERROR: Please run 'az login' to setup account.
```

what's the trick to run custom github actions that depend on the login? is this action exposing the required ENV VARS which are needed? I know for a fact that my client id has enough permissions since inline az commands works, but that forces me to only use "composite" actions and not Docker actions.
