Find alerts in SPO library using CSOM

Question

How can I find alerts set on my lists using CSOM?

If necessary, I have the alert GUID and I have the list GUID

Alert={391EDCAC-BDC0-4561-8E86-5291E3323CF8}

List={E613438C-0DF1-429B-9087-0D01D4E0ACBF}

How can I retrieve it and its properties?

1. It is not under $List.EventReceivers (collection is empty)
2. There is no $List.Alerts collection
3. The alert is not listed under $ctx.Web.EventReceivers, nor $ctx.Site.EventReceivers.
4. None of the properties under _api/web/siteusers seems to be related to alerts, so it looks like the alerts are not attached to the users.
5. http://<Site>/_vti_bin/Alerts.asmx tells me that it is for a local server, not for SharePoint Online.
6. I am aware of UI possibility "Manage my alerts". I did not manage to find where it pulls the alerts from.

The alerts must be located somewhere. Please help me find where.

Years later,

alerts can be found at $web.Alerts
This applies not only for the alerts at the site level, but also for list alerts and even item alerts.
