this is how I do it:
AJAX request:
open the session map set the visibility of the layer and possibly the groups recursively to true, save the session map.
After response: refresh the map.
This works with the fusion viewer.
But in the legend of the react layout the layer remains not visible (not checked) and the next request GETDYNAMICMAPOVERLAY contains this layerid in the parameter hidelayers.
so my idea was toggle the checkbox in the legend but don't no how.
setLayerVisibility(layerid, true) or setLayerVisibility(mapname, {id: layerid, value: true}) both don't work.

Normally I would call the server side request to toggle the layer visibility with a _javascript_ ajax call
and then just use _javascript_ to refresh the map without reloading the page.
