Open an external URL when I click an issue action option in the forge custom UI

Hi all,

I want to add a new option called ‘Create Change’ in issue action item, please see as below. I have already added it with custom UI, but how can make it open an external URL when I click this option? Can we add onClick in the manifest.yml file?

Any suggestions would be greatly appreciated.

Best Regards,
Danny

Does anyone know this?
