can anyone help me find a way to add a group to an organization?
It seems to be useful and necessary and I did not find any related article.
I rather find a way without Installing Add-ons but if there's no other way, I would be happy to introduce me suitable Add on.
There is a feature suggestion for this in the product backlog that you can track here: JSDCLOUD-4867. According to a rough estimate from March this year, it may be roughly expected by the end of this year.
You can watch the ticket to stay informed of future updates.
Hope this helps!
