Hi,
I have these workflows

I created a developper group with multiple users.
I would like that only users on developper group have a visibility on OSBL&OSQ issue type.
I have seen that some posts say that this is not possible, but they are old publications. Maybe is it possible today.
I have few clues with Issue Security Scheme and post function but I do not know how can I do ...
It would be great if someone can help me !!
Kind regards
