Buttons to choose 'hover to closest' and 'hover to compare' disappear in versions from 2.0.0 to 2.3.1. See repo here https://codepen.io/zyzhu/pen/BaREOVg

Buttons are there in 1.58.4

If I change version to plotly-latest.min.js. The buttons show up.

You could use v1hovermode or hovercompare, hoverclosest, togglehover and togglespikelines in config similar to this codepen. Please see #5654 for more info.

In addition you could use layout.modebar.add. Please see #5660.

Thanks for pointing that out. I didn't find v1hovermode, hovercompare, hoverclosest in the documentation here https://plotly.com/javascript/configuration-options/#remove-modebar-buttons. Adding togglehover only does not work. Maybe the documentation shall be updated.
