one of my Tableau report is linked in cognos portal. When user click on the report name that basically hit the "Published url of the tableau report" feeded into cognos. But the issue is it is opening the same tab of the browser instead of opening into new Tab of it. I also append the "?:linktarget=_self&:embed=yes" ?:linktarget=_self&:embed=yes" to the end of the url shared with cognos but no luck.
