Jira automation Rule

[Sharadkumar Bangera]

My requirement is

I have created 2 ticket lets say 'Ticket 1' (Parent) and it's clone 'Ticket 2' (Child).

If anyone add any comment in cloned ticket "Ticket 2" And change the status to Done, it should copy the comment from Ticket 2 to Ticket 1 automatically

Please suggest script step by step or automation rule if applicable

I am using "Automation for Jira" addon app
