It is not in a super easy place to find.  This post help me find it.  It is in the gear icon.

- Click on your user name on the left and then in middle section of the page click the gear icon.
- Then you should get a "Reveal NWC" option

Just testing if I did it right. NWC

Double checking a few things:

- You put your NWC string from coinos into the "connection for sending" field in SN?
- In SN is there a green or grey circular for NWC in the attached wallet section?
