Help with updated cover please

[Lauren]

Hello!
I want to update my book cover for this book, and I am so confused as to how! I saw I think that I need to create a completely new book and then somehow merge them? Is that correct? I know GR doesn't delete covers of published works, but as the above is yet to be published, is it okay to instead just to a straight swap?

Have there been any ARCs in any form using the current cover?

[Lauren]

None. ARCs have not yet been sent out (it's still in proofreading)

[Abcdarian]

Cover deleted. Go ahead and add the new cover.

Thanks so much :)
