Is there a non-browser version? Id love to sign in with Amber, but it wants my browser extension signer.

Just added a bunch of folks I know and have been interacting with on here for the last couple years... Also wanted to add @Contraband Joe, but he's a very new profile (so I think that's why it wouldn't let me tag it?) They came to nostr just days ago, by way of Agorist.Market (I know them too)
