How do I claim it? Just putting it in the nip05 box?
Discussion
It seems you have already claimed your username so either click the button on Settings / Iris account (Set as primary Nostr address nip05) or set it manually (edit profile).
I ctrl/r and then click in yes and nothing happens. I guess I try later maybe it works
Iris.to/kensei works. You can change the nip on the edit profile section if you like (kensei@iris.to) or use your current one.
Thank you!
