What is the id of this menu?

I don't know exactly but here is what I found in the repo: https://github.com/JetBrains/intellij-community/search?q=%22Modify+Run+Configuration%22 You can try to dig deeper along these ids.

I hope this is useful.

Hi Sorin,

You can also use UI Inspector to retrieve any action ID:
