R: Add title to Leaflet map

Question

I'd like to add a title to the whole map (different from the legend title: addLegend(..., title = "", ...): by "title", I mean an overlaid map component that stays in place while the map is moved (unlike an overlaid image).

Is that an option in RStudio's leaflet for R?

leafletR has a title="" argument but it updates the title of the webpage: it does not add a title to the map.

@MLavoie's idea is correct, but I was looking for something more specific like this:

tag.map.title <- tags$style(HTML("
  .leaflet-control.map-title { 
    transform: translate(-50%,20%);
    position: fixed !important;
    left: 50%;
    text-align: center;
    padding-left: 10px; 
    padding-right: 10px; 
    background: rgba(255,255,255,0.75);
    font-weight: bold;
    font-size: 28px;
  }
"))

title <- tags$div(
  tag.map.title, HTML("Map title")
)  

map_leaflet <- leaflet() %>%
  addTiles() %>%
  addControl(title, position = "topleft", className="map-title")

This will center the leaflet-control title as shown in the screenshot and place it at the top.
