Help setting up My Cloud EX2 Ultra please!

Hi - very limited tech knowledge here. I am attempting to set up My Cloud WD EX2 Ultra. I’ve got as far as creating a password and am now being asked to enter Device Code but cannot find it. There is no sticker on the bottom as suggested. There is a sticker on the back of the device but cannot see a device code. Please help! Thanks in advance.

Update - I just tried something different. I went to mycloud/setup and entered my new password using admin as username and I have access to this

So do I not need to enter a device code after all? No idea what I am doing!
