Stuck un 'Press home button to upgrade' with broken home button

Hi everyone,

I'm using an SE 2nd Generation and my problem is the following:

After resetting my phone because of storage issues I wanted to restore the latest back-up from my Mac. The back-up seemed to work but once it had ended up restoring, it led me to the "Press Home Button to Upgrade" page. Now the problem is that my home button is broken and I can't press it but I also found no other way how to get into my phone.

It doesn't appear on my finder anymore when I connect it to my Mac so I also can't just try a fresh restore from the back up.

I had both the iPhone and the Mac updated to the latest software versions.

Any idea what I could do? I'm completely desperate.
