How can I use dataset of a tag?

HTMLElement has dataset as property (e.g. data-foo). How can I use that with VanJS?
I see that each element have dataset as property but I don't know how to use it.

const Tooltip = () => div({class: 'tooltip', dataset: {foo: 'my-bar'}}, // results in error
  div({class: 'avatar'}),
  div({class: 'line'}),
  div({class: 'line'}),
)

Try this:

const Tooltip = () => div({class: 'tooltip', "data-foo": 'my-bar'}, // results in error
  div({class: 'avatar'}),
  div({class: 'line'}),
  div({class: 'line'}),
)

Yes, that works.
Hmm so dataset is useless haha
