How to display calendar events on lockscreen in Oreo? There are similar questions for previous Android releases.

Is it possible in Android 8 Oreo on a stock Nexus 5X to customise the lock screen to display upcoming calendar events? Google Pixel 2(XL) allows this.

(the image is of a home screen, but the question is specifically for the lock screen)
Calendar notify does a great job showing the agenda using persistent notifications.

If you'd like a more stock look, and if you are willing to root your phone and install the xposed framework (after it is released for oreo), then EventLock (disclosure: it's written by me) is what you are looking for.
