Custom HTTP notification

Hi.
I want to set up custom HTTP notifications. I found some information at Upgrade Alert Notification Type "HTTP Notification" · Issue #734 · Graylog2/graylog-plugin-integrations · GitHub, but I couldn’t locate the relevant configuration options in the Graylog interface. Could you please advise me on how to implement custom HTTP notifications in Graylog?

At this time graylog currently does not support custom HTTP notifications. However, this feature is being developed (I’ve tested it and it works wonderfully) and should be released in the next major version of graylog.

Custom HTTP notifications was released with Graylog v6.0. See Alert Types
