Scheduling job to run on 1st of every month

I would like to know a way to schedule my job to run on 1st of every month. Currently I dont see anything that would help me to do so. If I use interval with minutes as 43200 (30 * 24 * 60), the problem is with months with 31 days. Any leads or references would highly be appreciated.

Jobs trigger on resources finding new versions. It looks like the time resource only allows s, m, and h but there’s nothing stopping you from making a new resource or using another one. There is a cron resource but it hasn’t been updated in a while.
