How can I launch a custom confirmation dialog during a Jira workflow transition?

I intend to develop a Jira plugin that presents a confirmation dialog during workflow transitions instead of enforcing strict validators. How can I intercept transitions for custom action?

In my experience, the key to launching a custom confirmation dialog during a Jira workflow transition lies in intercepting the transition call in a way that lets you inject your own front-end logic. I solved a similar challenge by extending the Jira web interface using custom web resources within my plugin, which allowed me to trigger an asynchronous confirmation modal before completing the transition. This approach required some careful work with the Jira plugin framework to ensure that both the front-end and back-end were properly synchronized. I had to implement custom logic that blocked the transition until the modal was either accepted or rejected, and though it was a bit fiddly at first, enhancing error handling and resetting state improved overall stability. Overall, you need to integrate your modal into the transition flow without disrupting the built-in validators and conditions.
