Can you provide user guide about Javascript callback?
I've read documentation at Interaction — Bokeh 3.3.2 Documentation.
In particular, I'm interested about TapTool, but only given a guide about OpenURL. I don't see how custom tap callback works.
And how to best explore javascript variable in Jupyter? How to inspect data from cb_obj, and cb_data?
Should I just try to create standalone html file and learn javascript callback from there?
