Webook - mirror 2 instances

[Amali]

Hey Community,

I have the following requirement.
There are 2 projects in 2 different instances. If an issue is created in 1 project in instance A or an update happens, both instances A & B need to register it. For example, if an issue is created in 1 project in instance A, instance B should create the same issue. If there is an update in issue in instance B, the same issue in instance A should reflect that update (bidirectional). How to set this up in Jira using automation webhook? I succeeded in creating an issue both instances. But updating doesn't work. If there a way to mirror all changes in any instance in the other?
