Recovering photos from unresponsive iPhone 5s

My iphone 5s is suddenly unresponsive.

It turns on just fine, but doesn’t recognize screen touches.

I thought it was a screen problem at first and took it to a repair shop, but the guy told me that the problem was the motherboard and that the phone shouldn’t even be turned on

I logged in to icloud on pc to find out that somehow, the phone has a backup from yesterday, but the icloud photos didn’t have any of my photos from the phone.

I really need to recover the photos.

What should I do?

(The phone CONNECTS to iTunes, but I can’t process anything on the pc because I have to push the “allow access” button on the phone to enable access on the pc. And the phone doesn’t recognize the touch)
