Coupling tooltips on hover between subplots using r and plotly

I would like to do a plot like this one: https://www.somesolvedproblems.com/2020/03/how-to-link-plotly-events-between-plots.html

Here is what I have tried:

library(tidyverse)
library(htmlwidgets)
library(ggplot2)
library(plotly)
library(shiny)

x <- seq(0,1, 0.001)
y <- sin(2*pi*x)
z <- cos(2*pi*x)

df <- data.frame(x = x, y = y, z = z)

p <- ggplot(df, aes(x, y)) + geom_line()
q <- ggplot(df, aes(x, z)) + geom_line()


r <- subplot(p
           , q
           , nrows =1
           , titleX = FALSE
           , titleY = FALSE)

r$elementId <- "rt"

s <- r %>%
    onRender("
    function(el) {
    el.on('plotly_hover', function (eventdata){
    console.log(eventdata.xvals);
    Plotly.Fx.hover('rt',
                    [
                        { curveNumber: 0, pointNumber:eventdata.points[0].pointNumber },
                        { curveNumber: 1, pointNumber:eventdata.points[0].pointNumber },
                    ]
    );
    
    }
  ")

with hints from: https://community.plotly.com/t/coupling-hover-events-for-side-by-side-subplots/2049 and https://plotly-r.com/js-event-handlers.html

However, this does not work yet. Primarily, because of my lack of understanding of the javascript issues. Is such bidirectional trigger possible? Can this be done using plotly package and related tools such as htmlwidgets and htmltools package for r? Thanks.

El issue no proporciona ningún archivo del repositorio ni ningún punto de entrada de prueba. Empieza reproduciendo el ejemplo de R con subplot(), htmlwidgets::onRender() y Plotly.Fx.hover(), y después define un comportamiento de hover bidireccional compatible y un ejemplo o prueba ejecutable como criterios de finalización.
