Sequencer and "keep state"

I have a simple sequencer animation on a mesh (which works correctly when being triggered from blueprint) which affects only translation. I want to keep the position on the mesh after the sequencer animation has finished. I read about right click → properties → when finished → keep state. But this simply does not work in any way. Any idea what I am missing?

I answer my own question: the actor in question needed to be set to “posessable” instead of “spawnable” in the sequencer.

Can you please explain how you did it?
