Calling custom Event in Level Blueprint from Sequence

Tried to follow the example here Calling Events through Sequencer | Unreal Engine Documentation

I have a Custom  Event called ‘CarDissolve’ in my Level Blueprint.

In my Layer Sequence I have created a new Events-Trigger track and created a keyframe.

When I right click the keyframe and go to Properties > Event > Quick Bind  I cannot select my Custom Event.

What am I doing incorrectly?
