Unlikely that you're still stuck, but for others:  the blade that comes with Umbra is pre-loaded with mods that help you fight them, AND Umbra has those equipped for his 4 ability - both of these can help.

I found it extremely difficult to beat the sentients with a frame I had no experience with, so the main thing you need to know is:  hit 2 to blind them, and then hit 4 and just spam melee attacks. When they wake up, hit 2 to blind them again. Hopefully you can kill them before you run out of energy.

Since you can adjust mods before the final mission, take that moment to add some +energy mods to Umbra.
