Just added, sorry, my first post (but I pasted it...)

why it is writtent in Google Docs -_- ? I have made an online preview, but it is just special repo which is hosted book in .pdf

Thanks, I will

https://github.com/AnMnv/eBook/blob/main/eBook.pdf here is just the link on .pdf book but the names in TOC in not "clickable" that is why I choose online preview in this way)

in this case, downloading starts immediately, it is not ok (at least in my case, I want to have online preview)
