Transfer eBook between Windows 10 PC and iPhone7Plus

Please excuse me as  I am a novice to Adobe ADE 4.5.11

Just downloaded Adobe ADE on my Windows 10 PC and iPhone. Authorized both with my Adobe Id.

I have  to transfer e-book from Adobe ADE on Windows 10 PC to Adobe ADE on iPhone that is connected via USB.

Please refer to

There are two sections related to transfer:

Section 1 : Transfer eBooks between computers

Locate the book you want to copy, and transfer it to the other computer.

Section 2 : Transfer eBooks from or to a supported eReader

Connect the supported eReader device to your computer and launch Digital Editions. Digital Editions automatically detects the presence of your device.

Qn. Is iPhone considered eReader and should I expect it to appear as a device on PC Adobe IDE?

I do not see iPhone as a Device under ADE 4.5.11 on my PC.
