First of all, thanks Matt and the other collaborators for all the effort you have put into this package.

I have more of a question than an issue, per se, but I wanted to know whether it is possible to add shapes to the plotly object resulting of timetk's plot_acf_diagnostics (and in extension, to plots resulting from other timetk's functions):

The result I want is something like this:

Just as you can do with base plotly, as described here, for instance:
https://plotly.com/r/shapes/

The code I'm trying is:

library(timetk)
library(tidyverse)
library(plotly)
 taylor_30_min %>% 
  plot_acf_diagnostics(date, value,.lags=1:48) %>% 
  plotly::layout( title = 'Test',
          shapes = list(
            list(type = 'circle',
                 xref = 'x', 
                 x0 = 2, x1=5,
                 yref = 'y',
                 y0 = -0.1, y1 = 0.4,
                 fillcolor = 'red', line = list(color = 'red'))))

Is there some way to do this with timetk + plotly? What I am missing here?

Thanks in advance!
