Iphone 7 - how to restart after reset to factory installation without a working hone button

I reset my iphone 7 to zero using erase all as I am about to sell it. My pushhome button does not work wherefore I used the digital home button.

now after the reset, the phone wants me to push the home button (which does not work) to get started and my digital home button isnt visible as it liklely disappeared in the reset.

Great if someone knows how to resolve?

Kind regards M
