Can my widget handle a shiny message?

The rgl::rglwidget() function creates an htmlwidget that works in Shiny. It is integrated with crosstalk, so you can use the mouse to select items, and they are highlighted in the rgl display as well as in other linked widgets. This is somewhat similar to the brush in Shiny plots.

In Shiny, the session$resetBrush() method clears the brush. Its source contains this:

private$sendMessage(
        resetBrush = list(
          brushId = brushId
        )
      )

My question is: can set up my rgl widget to receive these messages, or do I need to create my own custom message to do the same thing?
