Anyone know how to stake $ogXen?

Seems that at times, there is demand for $ogXen. Perhaps it's not too hard to do directly on a block explorer?

ArneEvertsArts Yes sir, thank ye. I do see on XenMon that I have $ogXen 13M sitting in a stake, and at least, I would like to be able to unstake it.

There should be a way to unstake it just using the block explorer, but I don't know the specifics required. Does anyone know?
