How to highlight selected polygon in interactive map, made in tmap package in R?

Question

For example, I made a simple leaflet based map using tmap package. The result is an html with interactive map, showing some polygons of buildings (find data, code and the map itself here).

I want polygons to be highlighted someway when selected by html user by mouse click, like it is in QGIS (screenshot adjusted). Is there a way to do such thing in R?

You may consider switching over to library(leaflet)

map <- tm_shape(buildings) + 
  tm_polygons(col = "#ff00bf")

leaflet(data = buildings) %>% 
  addPolygons(highlightOptions = highlightOptions(color = "yellow",
                                                  weight = 2, 
                                                  fillColor = 'yellow', 
                                                  bringToFront = TRUE))
