Unfortunately, implementing "prev" link is not possible for now as we provide only the 'next_offset' and not the 'prev_offset' in our API, Sorry.
We'll certainly let you know if the option is made available in the future.
We would like to get a bit more insight on your suggested implementation? Could you please explain?
Thanks for your valuable suggestion. I've notified our engineering team regarding this and we'll get back to you if they consider and take this up for implementation.
