I have a Google Group set up as part of the Google Suite (basic account). When creating the Google Group, I set the "Join the Group" permission to "Anyone on the web".
How do people now join the group?
I tried pasting the standard join link in an incognito tab:
https://groups.google.com/a/example.com/forum/#!forum/examplelist/join

Authorization Failed
This group is on a private domain.
