How Can I Group Switches for Alexa Discovery

I have 5 light switches that I would like to group together so that I can ask Alexa to turn them all on or off at the same time.

I read the following but not sure where/how to implement.

It is important to note that you are exposing Items not Things or Channels. 
Only Color, Dimmer, Rollershutter, Switch and Group type Items are supported. 
Group type items require the "Huelight" tag to be exposed as devices instead of Groups.

I have created the following but not sure how to fix to be discovered.

This is what Groups are for. Create a Group:Switch, apply the “Huelight” tag and add all your light Switch Items as members of this new Group. Sending an ON command to the Group will be forwarded to all the members of the Group.

Thank you for such a fast response.

It’s unclear to me where to add the “Huelight” tag.

This is what I have done via the UI.

Put Alexa into DISCOVERY (Device Pairing & Pairing: Temporarily Emulate V1 Hue Bridgemode) but Alexa did not find it.

Should I be creating the Group:Switch via an .items file?

According to that screen shot it’s already there. Under tags the second entry is “Huelight”. I don’t use Alexa nor hue emulation so beyond that I can’t help.
