Retrieves a group by slug.
The slug is the end of a group's URL that refers to a specific group.
For example, if a group's URL is https:/example.com/groups/{my-fitness-group}, the slug is my-fitness-group.
Slugs are case-sensitive. It is generally based on the group name, but for secret groups it is an autogenerated string of characters,
for example, https:/example.com/groups/{5D3yTX}.
For groups with group.privacyStatus set to SECRET, only group admins and group members can see the group and its content.
Unique part of the group's URL. For example, if a group's URL is https:/example.com/groups/{my-fitness-group}, the slug is my-fitness-group. Case-sensitive.
