Detect one or more rows selected in an attribute table from an add-in

With ArcGIS Pro SDK 2.5, you can detect that the map selection has changed with the MapSelectionChangedEvent, which also includes selecting one or many rows in the attribute table of a geodatabase that is loaded in a MapView. I know that I can wire it up like:

private SubscriptionToken eventToken = null;
private void SetupEvents()
{
eventToken = MapSelectionChangedEvent.Subscribe(OnMapSelectionChangedEvent);
}
private void OnMapSelectionChangedEvent(MapSelectionChangedEventArgs obj)
{
//do work on the selection
}

I would prefer to isolate the work in the handler to only happen when the geodatabase's attribute table row selection changes, not on all map selections. I haven't been able to find an event that fits this qualification in the sdk. Does one exist?

EDIT 3/19/2020: Since it may be unclear what I'm attempting to achieve, the below image has the MapView and the open attribute table. I would like for the selection of a row in that table to trigger an event in my add-in. The MapSelectionChangedEvent is far too broad for this purpose, so if there is a SelectionChanged event or the like on the attribute table that I can hook into, that would work. I cannot seem to find one, though. I can select something from the add-in and have it show on the map, but I wanted to know if something existed on this built in control.

After contacting ESRI Support, there is no way to actually achieve this through a singular event, but you can do them in tandem.

The suggested approach was:

private SubscriptionToken eventToken = null;

private void SetupPaneEvent()
{
eventToken = ActivePaneChangedEvent.Subscribe(OnActivePaneChangedEvent);
}

private void OnActivePaneChangedEvent(PaneEventArgs args)
{

   //The window that is selected is a table, so then register an event that handles selections
   if (FrameworkApplication.Panes.ActivePane is ITablePane)
   {
       eventToken = MapSelectionChangedEvent.Subscribe(OnMapSelectionChangedEvent);
   }
   else
   {

   // not a table? Unsubscribe.
       MapSelectionChangedEvent.Unsubscribe(eventToken);
   }
}

private void OnMapSelectionChangedEvent(MapSelectionChangedEventArgs args)
{

//Do work that detects which source and how you need to filter out different actions between feature classes

//and stand alone tables
}

Did you ever run into GC issues and need to use keepSubscriberAlive like mentioned in the following ticket?

https://community.esri.com/t5/arcgis-pro-sdk-questions/sketchcompletedevent-firing-only-sometimes/m-p/1323595

I'm using your approach and everything seems to be working well whether or not I use keepSubscriberAlive but maybe my tests aren't rigorous enough.
