How to show Tooltips in UXP plugin in

Is there an example showing the use of tooltips (or is it bubbles?) for Photoshop UXP?
I saw this but it is quit old and reference XD.

<div title="Your tooltip">Content</div>

This just shows the “Content”.
Title is not shows when I hoover over it.
In my CEP panels I used to add js+css for the tooltip to work.

Where is the .js and/or css for the div titile?

Please use forum search more often. Currently title is the simplest option and it usually works when you hover and wait a bit. Of course you can build your own like I did in one of my plugins, but sharing would be very difficult - it’s tightly coupled with plugin and is very specific to it.

I’ll create my own.
