phpIPam LXC, how to configure scheduled scans/SNMP

Just spun up a phpIPam LXC from Helper Scripts and it seems to be working. Typically phpIPam uses /var/www/html to pull in SNMP scans and crontab for scheduled tasks but in the LXC phpIPam resides in /opt.

Just want to understand how to configure scheduled tasks in the LXC because no guide I've found yet addresses an LXC. If need be I'll just spin up a VM and go that route or build my own LXC but figured I'd ask if anyone is using the pre-made LXC first.
