I finished the quest getting the stones from the lesser invasion points.

I am granted the ability to enter the greater invasion point. And…it's just me. No group.

I figured I would be auto grouped when I entered the greater invasion point just like I am auto grouped in the lesser invasion point. But that did not happen.

I went in and out of the greater invasion point instance…no change.

I did not see any tool to "find a group" like we sometimes see with world quests.

Please Help.
Thanks !
I didn't find the right solution from the internet.
