We have a rather large set of groups defined in our system, and we are looking to determine which groups are actively being used, and which we might be able to remove. I'm not sure how to tell which groups are being used in Bitbucket. I found this post on Jira groups (https://confluence.atlassian.com/jirakb/how-to-identify-group-usage-in-jira-441221524.html) very useful; is there similar such documentation for Bitbucket? (... and for bonus points, Bamboo?)
