Argo Rollout notification add some delay

[ajax-bychenok-y]

I wish to send argo rollouts on-rollout-completed notification with scaleDownDelaySeconds (Rollout parameter) delay.

Looks like I need to use when: condition and I see an example from Argo CD project https://argo-cd.readthedocs.io/en/stable/operator-manual/notifications/triggers/#functions:

when: time.Now().Sub(time.Parse(app.status.operationState.startedAt)).Minutes() >= 5

app.status.operationState.startedAt is Argo CD yaml field, so I need similar Rollouts field but I can't find such.

Is it doable with Argot Rollouts? Can somebody push me in right direction?

I need something like

kubectl get rollout k8s-dummy-svc -n sandbox-shared -o jsonpath='{.status.conditions[?(@.reason=="RolloutCompleted")].lastTransitionTime}'

2025-03-25T23:16:56Z%

But @ is unrecognized character in argo rollouts notifications:

    trigger.on-rollout-completed: |
      - send: [rollout-completed]
        when: time.Now().Sub(time.Parse(rollout.status.conditions[?(@.reason=="RolloutCompleted")].lastTransitionTime)).Minutes() >= 5

{"level":"error","msg":"error getting api from namespace: argo-rollouts error: unrecognized character: U+0040 '@' (1:56)\n | time.Now().Sub(time.Parse(rollout.status.conditions[?(@.reason==\"RolloutCompleted\")].lastTransitionTime)).Minutes() \u003e= 5\n | .......................................................^","time":"2025-03-25T22:50:45Z"}
