Hi,
How can I configure a two-way sync Jira Cloud between MS Teams?
The answer can be third-party solutions 
I have a bunch of customers’ channels, one channel for each customer.
E.g., when I have a ticket from customer Contoso, I would like to open a thread to talk about the specific ticket DNX-0123. Every message exchanged on this thread will automatically synchronize with the Jira Ticket and vice versa. When a customer or my Service Desk agent adds a comment to the Jira ticket, it will appear in the Teams thread.
Can we achieve this scenario?
Cheers, Wilson
