Implement "Behaviours" like ScriptRunner Server/DC#4

As a user,
I want to set rules on issue fields that changes how they behave when used,
So that I can implement my preferred processes

My team is moving from Jira Server to Cloud, and not having behaviours is going to break a lot of our Jira automation. We use behaviours and rest scripts to retrieve external data from a data store based on what values a user chooses in custom fields during issue creation.

Being able to dynamically make calls to external data sources during issue creation is an amazing feature of behaviours, and I absolutely would love to see this functionality come to Jira Cloud.

Hi Team,

Kindly consider to implementing Behaviour concept in Jira cloud, really it helping us to showing dynamic data, forms and custom field.
