如何在传单Map上添加按钮以显示和隐藏以下r代码中的datatable部分：

library(leaflet)
library(DT)
library(crosstalk)

df <- read.csv(textConnection(
    "Name,Lat,Long
    Samurai Noodle,47.597131,-122.327298
    Kukai Ramen,47.6154,-122.327157
    Tsukushinbo,47.59987,-122.326726"
))

sdf <- SharedData$new(df, df$Name)

bscols(leaflet(sdf) %>% addTiles() %>%
    addMarkers(~ Long, ~ Lat),
    datatable(sdf, width = "100%"))

需要添加一个按钮来处理显示/隐藏datatable部分，如下图所示：
