Question on how to uses coolconfig

Hello

I have few questions about using the coolconfig command line tool that I don’t seem to be smart enough to figure out on my own.

  1. Is there a way of using this command to show what the current value is set too?

  2. From the googling I have done, it looks like command sudo coolconfig set storage.wopi.host nextcloud.example.com often seen in how to guide no longer work the way it was originally was intended. It gives a No property, "storage.wopi.host", found in config file. error, which I don’t remember seeing before. How would you issue this type of command now?

  3. I think this related to questions 2, but how would you set up two Nextcloud instances, e.g. nextcloud1.example.com and nextcloud2.example.com. That is, have to separate installations of Nextcloud uses one installation of Collabora.

Thank you
