Screen Dead - Need to disable alarm topic

Hi. My screen is dead on my phone. I need to somehow disable the alarm.

I cannot seem to find where the alarm data is stored.

I then tried to delete the apk.
I got an ADB by booting into TWRP. Then used ADB SHELL. I attempted to cd into System/App as follows

cd system/app
/sbin/sh: cd: can't cd to system/app

I figured I had a root permission error, so I tried "su" but it couldn't find the command which is odd because I have SuperSu.

I can't navigate the TWRP menus due to my broken screen and don't know what to do.
