I used the nostr:npub1tnpfz60snm7ler8k8c69335n37we6690qttl88t556yzkjxhahjq3kkkpe signing extension. I had already installed it and granted it permissions to sign events for those 2 web apps before doing the screen recording.

I was using this too before it was removed from test flight. I've reinstalled it but doesn't seem to be working. I don't think nostore works with snort as a progressive web app either.
