Missing Groups Logs When Using Events API?

Hello,

I am setting up some alerts based off of the Okta System logs. I am trying to find logs where the event type = group.application_assignment.remove using the events api. I can easily find these logs using Okta’s System Logs tab, but when I try and find the same log using the events API, they do not appear to exist? Same with the log associated with adding a group to an apps assignments.

Any thoughts?
