OpenBeken Equivalent to Tasmota Backlog Command for Doorbell Trigger

How do I do the equivalent in OpenBeken to the following in Tasmota?:

http://<ip>/cm?cmnd=Backlog Power1 ON;Delay 5;Power1 OFF

The Delay command does not appear to be implemented, so the relay closes and then immediately reopens again, without the half a second pulse. I'm trying to trigger a doorbell from a single http command.

To answer my own question...
