Update parent epic remaining estimate when a child issue's worklog is added

[Elizabeth Trambulo]

Using Automation for JIRA....

When a user submits a work log for a child story, I'd like to update the parent epic's remaining estimate (remaining estimate = remaining estimate - work log). I'm a little stuck with the syntax of setting the remaining estimate when the timetracking is a related object to the issue not a first class property.

{
"update": {
    "fields": {
        "timetracking": {
              "remainingEstimate": "{{issue.fields.timetracking.remainingEstimate}} -
 {{worklog}}???"
        }
    }
}
