title: R googleway: add a title on the map?
body: <p>Could anyone share an example on how to add a title on the google map? </p>
  
  <p>I tried using add_markers, but those are for particular locations. I searched online for an example but none available. </p>
  
  <p>Looking for something similar to leaflet package function <em>addControl</em>.</p>
