After reading all the comments, I think the best solution is to buy a used Ascend P6 and swap the displays.

if you can find an identical phone you can try to enable adb blindly by touching the areas on the screen, then use scrcpy
but in that case maybe just easier to enable mtp via usb
The screen is completely shattered and glitching, it won't work unfortunately..
Does it still display stuff? Then you could just connect a mouse.
Is the screen visible? You could hook up a mouse
Even without the screen it might be possible to enter a passcode with a mouse or keyboard. Once it's unlocked it should be able to be connected to a PC over USB and copy off all the data.
