pip install azure-iot-hub succeeds, but 'iot' folder does not exist

On a Beaglebone Black, I want to run some python code making use of this package.
The device is on Debian 11. Using python 3.9
Virtual environment is selected with source activate.

After running pip install azure-iot-hub or pip3 ..., the install process looks as normal.
Yet python code fails to run when trying to import the modules from azure.iot.hub.

When taking a look at venv/lib/pyhton3.9/site-packages/azure, "iot" folder does not exist.
After searching online, it popped up several times. People suggested to build the wheel locally.
This is not a good idea since the beaglebone has really limited hardware.

We can download the "wheel" on pypi.
When I do pip install ...whl, it gives the same behaviour.

Yet when I just unzip and copy the 'iot' folder to venv/lib/pyhton3.9/site-packages/azure/, everything works as expected.
This is not a good way since it requires manual action and is hard to automate in pipelines. (in comparison to requirements file)

Is this expected behavior for armv7? Should this work or is just doing "pip3 install azure-iot-hub" wrong?

Start by reproducing `pip install azure-iot-hub` and the `azure.iot.hub` import on Debian 11 with Python 3.9 and ARMv7, then inspect the installed package contents. Done means the package installs from a requirements file and the import works without manually copying the `iot` folder.
