convert story points in hours via Jira automation or script runner

[Consulente Atlassian]

With Jira automation I would like to make sure that when I move from one workflow state to another, the story points of a story are read and a value in hours is calculated for the estimated time field. For example, for each story point, I would like two hours to be calculated. Is it possible to do this with Jira Automation or do I have to use Script Runner ?

I think a custom script is required. Not so difficult, but required.
