Behavior of Activate Stream Deck+ Touch Screen Configuration Group?

StreamDeck+ specific question here:

Does anyone know how to use action
"Activate Stream Deck+ Touch Screen Configuration Group"?
(I'm going to use "Activate TSCG" as shorthand for this below)

As far as I can tell, the only parameter for this is
"Touch Screen Configuration Group Name".

What happens if I have more than one group?
I don't see a corresponding Close action.

Can I open/activate a Group when another group is open? What's supposed to happen if I do?

Some initial testing on 4.715 shows the following behavior:

  • If I have a TSCG defined, it doesn't show up until I do "Activate TSCG".

  • If I have two TSCGs defined, I can swap them back and forth by doing "Activate TSCG" on one, then the other. This seems reasonable except for two things:

  1. Doing "Activate TSCG" closes the currently open Stream Deck (button) Group.
    Is this supposed to happen?

  2. it seems that there isn't a way to close a TSCG. Should there be?

(btw, I seem to recall that in earlier BTT versions it was necessary to close an open Stream Deck group (button group, not touchscreen group) before opening a new group, but as of the current version it seems that it is OK to open a Stream Deck Group when one is already open. Has this behavior changed?)
