How do you use Collaborative tags? Whats the Workflow?

Since some Version I see the entry for collaborative tags in Nextcloud. I also played a bit with it, but I do not get the Idea behind it.

Does someone have one or two examples how these Tags could be used? What are the pros and cons?

There is a little documentation to explain their system wide use.

  • access control
  • retention
  • automated tagging via workflows app

They are designed to be used by admins
