Open issue transition dialog via Connect JavaScript API

Hi all,

In our application, we need to transition issues, and quite often, the transition can’t be done as the Transition post-functions require some custom fields to be filled.
In Jira, this problem is solved by showing the Transition screen that asks the user to provide the missing values and shows validation results.

Do you have any ideas if we can use Javascript API to invoke this dialog? Or if there are any other ways to show the transition screen from the Connect app?

Thank you,
Yuri
