Coordinates of zoomed area highchart shiny R

[hmgs92]

I have this scatter plot where I want to zoom in an area and then subset a table to show only the data from the subsetted points. The first step is done by zoomType = "xy", but I'm having troubles on the second step. Could anyone give me a hint on how can I access the upper left and bottom right points coordinates of the zoomed area, so I can subset the table?

Thank you!

  fluidPage(
    column(width = 8, highchartOutput("hcontainer", height = "500px")),
    column(width = 4, textOutput("text"))
  )

server <- function(input, output) {      

  dscars <- round(mvrnorm(n = 20, mu = c(1, 1), Sigma = matrix(c(1,0,0,1),2)), 2)

  dstrck <- round(mvrnorm(n = 15, mu = c(5, 1), Sigma = matrix(c(1,.5,.5,1),2)), 2)
