Settling 6 month old puppy

I have a cockapoo just coming upto 6 months old. I pen trained her from day one and she goes in her pen and settles no problem. However she wont settle or fall asleep outside the pen. Will she eventually learn to do this?

I have tried waiting it out to see if she will settle on floor, sofa or me but she will just keep going and get bitey so have to enforce naps in the pen.

Any advice or similar experience appreciated.

She is a chewer so cant be left to her own devices unsupervised yet
