@RimIbrahim1 I would suggest that you add tags and you should also post on your profile that you have wrote a new book so that others will see you have wrote that when it pops up in there notifications
@XhulioNdrecaj you have to go to your profile
Then click on your works
Then choose the book you want to delete the chapter of
Then click edit
Then when you get on the edit page you have to click the chapter you want to delete
Then you click on the three dots in the top right of the page and then you click unpublish and it will unpublish that cahpter
