Can't connect Kobo to ADE (chromebook)

[#1]

I have a chromebook and installed the ADE app.  I'm trying to transfer a library book from ADE to my Kobo, but the instructions say to click on the devices tab in ADE to authorise it, but there isn't a devices tab at all, juste a library. There doesnt seem to be any place in ADE to add a device, or another version I can install on a chromebook. The computer does recognize the Kobo in it's files and it'S charging, and the books are in ADE and readable there, but I cant find a way to transfer them into the Kobo reader. 

Help, please.

I'm having this same issue. There's not even a device option on the app.
