How to reset password. Home button boken, recovery mode not working

I have a problem. I have not been using my iPhone 7 in many months, and I have forgotten my login pinkode. I need to either reset password or whole phone. I read you can do it in "find my phone" online, but I can't do that because phone is not connected to internet. I read you can also do it with iTunes, but then you need to enter "recovery mode" for the iTunes to discover the phone. I cannot ente recovery mode (home and powerbutton pressed for 10 sec), because my home button is broken.

I hope somebody can help me with this problem.
