PPTx files not available for download

This is a follow up issue to #6.

Thanks for sharing your materials on zenodo! Unfortunately, there are only PDFs and no PPTx files available for download: https://zenodo.org/records/11657763

If I had the PPTx files, I could reuse them (or figures out of them) and train for example my students at Uni Leipzig. Others could do so too world-wide and share knowledge about your work. Hence, consider sharing the PPTx files 🌞

Thanks!

Best,
Robert
