Can use DOORs NG client extension after opening MiniDashboard only

Hello!
I have found a serious constraint in extending of DOORs Next Generation v6.0.4 with Client Extension API technology. I developed a client extension which can be triggered after a user saves an artifact. And the JavaScript works well.
But the problem is that if the script will work only after user unfold the MiniDashboard panel at least once (after user loged in to DOORs NG). Next MiniDashboard can be hidden but it must be unfold at least once!
It's not good because the script automizes the work of users! But if they didn't unfold MiniDashboard, the script can not provide the necessary work.
Could you please recommend some workaround or another solution to cope with the problem? May be I was doing something wrong!
Thank you very much in advance!
