How do you read books continuously with Hoopla and Overdrive apps?

Hi all!

I have a question about OverDrive and Hoopla. I like to listen too books when I go to sleep, and I have been trying to find a way to do it with my library with Hoopla and Overdrive. What I’d like to do is have the book play continuously where I can skip chapters. I am trying to do it with ebooks and audio books. Because I like to listen to books on my iPad through my Echo via Bluetooth. I can read a books, but only at 1 chapter at a time. And audio books only stop playing if I close the app out. Is there a way to play books continuously? I am sorry if I am not making sense here. Any and all help is greatly appreciated! Thank you very much in advance!!
