Hello there! Yes, I am happy to share the files. I have both a dark and a light theme version of each template (20 different color themes in each).
They are PowerPoint files. However, if you upload them to your Google Drive, you then can open them using Google Slides and Google will convert them to Slides format. There may/will be some minor visual differences you will have to edit once they finish converting to Slides format.
Also, please note, each slide deck is almost 200 slides long, so they are large.

Happy presenting!
