Retrieve data from a broken screen iphone

See, I had an accident and all data from my late grandmother is currently on my old phone and I need to retrieve all this information to my new phone but guess what. I won't let me cuz I need to accept a code on the phone that has the broken screen and I can't do anything. my broken phone reponds from everything else but the screen.

I need help, please!!!! I have pictures from my grandmother there, voicenotes and stuff I would like to retrieve for the love of God.
