Using Web Component HTML tags with reflex

Question

I try to use Web Components in Reflex. Code is as such:

buttonUI5 :: DomBuilder t m => T.Text -> m (Event t ())
buttonUI5 t = do
  (e, _) <- element "ui5-button" def $ text t
  return $ domEvent Click e

For ui5-button it worked as expected. Other Web Components fire events not defined in Reflex.Dom.Widget.Basic like "liveChange".

How can I translate these into Reflex Events?
