How to pair a Bluetooth keyboard/mouse device without a functioning touchscreen

Is this possible?

The screen and digitizer are both gone. I'm able to successfully get to the homescreen via HDMI/MHL but from there I'm stuck since I can't open anything.

Please help!

Tapatalk app not functioning properly

So it logs me in, but it loads infinitely and nothing ends up loading in entirely. I've tried uninstalling it, deleting the data/cache but no luck
