APC UPS application integration

I recently tried to add my apc ups to librenms. While creating the dashboards I saw that librenms has applications built for the UPSs. I went to the site here (Applications - LibreNMS Docs) and followed all the steps described to add the application to my system. However, I am unable to see it on the web interface. I have followed all the steps described. Here are the last three lines of my snmp.conf file:

extend ups-apcups /usr/bin/sudo /usr/local/bin/ups-apcups
extend ups-apcups /etc/snmp/ups-apcups
extend ups-apcups/usr/bin/env PATH=/sbin:/bin:/usr/sbin:/usr/bin:/usr/local/sbin:/usr/local/bin /etc/snmp/ups-apcups

What should I do next to get this working? I tried polling and discovery as well.
