Undocked navigators NX9

[MarkosMark]

I can't find the solution here or anywhere else on the internet. I somehow undocked two navigators in NX9 and I don't know how to dock them back to the left. So my (probably simple) question is, how do I dock these windows back to the bar on the left

I have no idea what I did, but after a few hours it was suddenly back in its original position. For future reference and maybe other readers, if this happens again. How can you dock them back in their original location?

Right click on the tab to undock
Click the X on the upper right and it should go back to a docked tab.
