Micah-10 appreciates the help you have done with healing the Ghosts but more still needs to be done as the Witness still has forces around.
You will need to hunt down these enemies to put a stop to them and in return, Micah-10 will have something that will be helpful against the Witness.
This requires that you prepare to take on the challenge of facing some of the previous missions you have done with higher difficulties.

Convalescence: Budding Quest Rewards
After you have gone through the trouble of completing the challenging Cooperative Focus mode missions, you receive the Microcosm Exotic Trace Rifle.
Microcosm deals Kinetic Damage to enemies and does bonus damage to their shields, making it easy to make your enemies vulnerable.
Summary
After all the help that you have provided, Micah-10 believes that you have already done as much as you can for the Arbor of Light.
She mentioned that it is time to focus on taking down the Witness, which will be tough without the Vanguard and their allies.
The new Exotic Trace Rifle that you have plays a huge role in taking down The Witness and will prove to be a big help if you choose to use it.
