How to capture Xenon H?

[DTS]

So i found Xenon H in Tharka's cascade, it's empty and non-hostile, so there is no "Boarding" option. I thought i might get it as any other ship in my spacesuite, but i can't find entrance.

It took me 40 minutes to find it. To all who have the same problem - it's on top side close to the engines. Here's the picture https://c2n.me/4laHTuc
