javascript - Leaflet Routing Machine show option doesn't work

I am adding route to the map and I want to hide instruction (turn left, turn right etc.) but I want to show them later. As I can see there is parameter show for that. If I set show: false I see white squares instead of istructions which is ok, the problem is that I can't show instructions then by clicking on that squares, no interaction with them at all.

L.Routing.control({
  waypoints: [
    L.latLng(54.736985, 55.980878),
    L.latLng(54.732798, 55.969934),
  ],
  show: false,

}).addTo(map)

There is nothing wrong here I guess. What can it be then?
