For those interested on how to make it work, I added the instructions here: www.reddit.com/r/Onyx_Boox/comments/1hht7rf/demo_how_to_upload_your_boox_notes_to_notion
This is a demostration of the workflow I have built to export my Boox notes into Notion automatically, so that they are centralized in one place and easily searchable.
The idea was inspired by this blog post: michalwlosik.medium.com/automating-note-taking-onyx-boox-to-notion-with-ocr-and-ai-summarization-4a1d8ecd88ec
I tweaked it to make it work for my workflow and used make.com instead of zapier as it's a more affordable alternative.
