Labels of the annotation with Point Type?

Hey, can we add the labels to the annotations with the point type? I can't seem to figure out a way to do it.

This code is from the [documentation ](https://www.chartjs.org/chartjs-plugin-annotation/1.2.0/samples/line/labelVisibility.html) works pretty well with `line`, but changing the `type` to `point`, the tooltip stops appearing on hover.
