profiles renew -type enrollment, how often is the popup triggered?

We are currently enrolling existing Macs (not wiped) to our MDM using the command profiles renew -type enrollment.

We are seeing in some cases users are not clicking on the Enrollment popup that happens when this command is executed. Is there any documentation on how often this popup will appear to users? What happens if they X out of it.
