I would like the learners to see the slide notes after the eLearning is published. Is it possible?
Not by default. You can get the slide notes by exporting an MS Word translation document. The slide notes are all in a huge table right at the end of the document. But you will likely need to do copy/paste them into another document some reformatting to make them acceptable. Then you could offer a PDF of this document as a download at the end of your course module.
If you explained what you have more in the Slide notes, which is not in the course, maybe alternatives can be offered. Do you have audio? Use the CC feature, to show what is told also in subtitles, which are synchronized with what happens on the screen.
