They don’t let you do that yet. Your nostr:npub1earna05hx6ax38r33h3atmecjzdu547m8suw87w70aw6mlyga4hsqcja5j identity isn’t editable like other #nostr profiles. For now you’ll just have to send them manually.

They built a whole business on their ZBD address, don't count on being able to change this address to yours. At most, you will be able to edit it, but it will always be linked to ZBD domains. 🤷‍♂️
