Yeah, I tried that, but it gives only the option to examine it...
Starting from Day 2 at 19:00, I just did a quick run to double-check all of the steps.
1. Exit your cell.
2. Head right, investigate the vents near the bridge to play a few cutscenes.
3. Copy the Warden Key Card on the bed with your drone after the Sallika/Sai cutscene is over.
4. Return to your character, and interact with the map directly to your left in the same room, to locate the armory. (scroll through until it triggers the next objective.)
5. Go to the Class A cell (red-lit door) and unlock it.
6. Go inside, and you'll automatically talk to the alien leader there.
7. Head to the lab, and take the Spore Extractor from the wall.
8. Head left, and open the Class B cell, extract spores from the alien.
9. Head back to the lab, and interact with the Oxygen Capsule. You
should have an option to Examine, and to Release Spores.
