I need a button which does back command in non focus new tab

I want to create three button menu which with middle mouse click go backward in new tab can you help me?
I know how to create three button menu but my problem is how to create a button which go back in non focus new tab like pressing back with middle mouse click in google chrome.
Thank you.

Go BACK NEWTAB=nofocus should work.

I just tried it , but did not work. it goes back normally without creating new tab

Maybe

Go BACK 
Go NEWTAB=nofocus

It works here. Please show a screenshot of how you're using it.

That would go back in the current tab and then open a new tab.

Ok, is wasn't sure.

I uploaded a video.

and about

Go BACK 
Go NEWTAB=nofocus

this is not what I want . I want to keep my current tab at it's default position and go back in new tab for example in this video when I click on button I want to hold my position on "program files" and in new tab goes to "C Drive"

Works for v13, but not for v12.
