If you turn it on, it asks for permission on your nostr extension if your on the browser. If you are on mobile, you can generate a throwaway key. then it allows you to send and receive tokens inside your nutstash wallet over nostr!
When you send a token, you will get the option to send it to a nostr public key directly in the wallet. it will then send an encrypted dm to this account. If he is a nutstash user, the dm will show up in his nutstash wallet 😎
