@milevic & @Signfeld
Please try the following script, I have extended it with some of the ideas from this thread. Thank you @Signfeld for the discussion and bouncing ideas back and forth!
I believe that it is a better option than my script linked in the other topic.
This is still a hack to overcome missing features of Photoshop, which only allows one to:
Collapse All Groups...
But why not collapse the active group? Why not expand all groups? Why not expand the active group? ...However, I digress!
Note: Script updated 17th August 2022

Collapse Active Group.jsx

*** KNOWN LIMITATIONS & GOTCHAS ***
This script is a hack to overcome a shortcoming of the original implementation of layer groups/sets:
+ Layers clipped to the group will lose their clipping group property
+ Default layer names such as "Layer 6" may be auto-renamed by Photoshop to "Layer 10" etc.
