Problem Description

TheHive blog says that TheHive v4's API should be backwards compatible with TheHive3, but the version 3 API for follow/unfollow returns the modified alert object and the version 4 API doesn't.

Steps to Reproduce

Version 4:

curl -X POST -H 'Authorization: Bearer 7ywJAe8sk9v0qCPjWF0ysrc7+Q6JouTR' -H 'Content-Type: application/json' -H 'X-Organization: TestOrg' http://thehive4.local:9000/api/alert/82100472/follow
                                                                                                                                                                                                                                   ✔

I've checked and the "markAsRead" and "markAsUnread" APIs display this same behaviour.

@To-om is there public documentation available for the TheHive4 APIs? I was building a PowerShell API library and got it mostly working with TH3 okay, but finding TH4 just totally different and unable to find documentation on it.
