[BUG] select vertices by connection does not seem to work

i have tried several methods of using this node, none seem to work.
* just attaching an input mesh node to this does nothing
* attaching first a select vertice by index node then the select vertice by connections node does not work as per this example : https://youtu.be/tWhfj9otoYM

1. create input mesh (ico sphere)
2. create / connect Select by Index node (set to a number above 0)
3. create/connect Select vertice by connections node (set to 5)

Should select all vertices with 5 connecdtions
