I found the solution in this article :

It's not.

I'm not sure what your question here is, because:

• You say "successor" in the body of your question, does that mean "assignee" like you said in the summary?
• Are you asking how to implement something that sets the assignee?  If so, look to post-functions or automation

Hello!
I want to make an automatic assignment to the user who makes the transition to the status (presses the button in progress) . How can I do that ?

Um, as in the last sentence of my answer?

I would like to write this via a post-function, but I don't quite understand how yet. Unfortunately, I didn't find anything specific in the articles.
