Jupyter releaser for multiple Jupyterlab extension in a monorepo

Hi,
In the last months, I have been developing jupyterlab extensions for integrating jupyter lite (and maybe also lab) in an iframe. It is a set of extensions, where it actually can make sense to users to only install a selection of extensions and not all together.
So, I made a monorepo with a modification of the jupyterlab extension template.
Now, I would like to make my first alpha release, but I am a bit stuck configuring the trusted publisher at PyPI, as it requires a project name.
And I am wondering which project name I should select from the four packages. Or is there a limitation and I can not set up all the packages inside a single repo?
For reference, this is the repo:

And please be patient, I am actually not very familiar with python and its concepts.
Thanks!

GitHub - jupyterlab/jupyter-collaboration: A Jupyter Server Extension Providing Support for Y Documents uses a monrepo setup like this; in that case there is a clear umbrella package.

Ok thanks, and for pypi trusted publisher I would then use the project name of the mono repo? (in the example jupyter-collaboration-monorepo)

I don’t now. I think jupyter-collaboration does not trusted publishers?

I think it must use trusted publishers as I do not see pypi credentials in the yml for publication. I think I have also seen older screenshots from pypi, where the project field was not there.

Thanks for the help.
Here, for reference, is what I ended up doing.
pypi supports only one pending publisher at a time.
So, for the first release, only one package could be published.
One can either release multiple times until all packages have a pending publisher or manually do a first release. I did the latter after the error message from PyPI was clear.
