Inquiry About Project Attachment Awareness in Plugins

Hello JetBrains Team,

I am a developer working on a plugin for JetBrains IDEs, and I would like to gain a better understanding of the "Attach Project" functionality. Specifically, I am interested in knowing whether this feature can be detected from the plugin side.

If it is indeed possible to detect when a project is attached, I would appreciate it if you could provide guidance on how to access the different workspaces associated with this functionality.

Thank you for your assistance!
