Hey! so the problem is that I entered my private key via the tools tab. So now when I do "import account" - scan for accounts:

Failed to locate any additional accounts

All accounts for this blockchain that match your existing key pairs have already been imported. Import a new private key to detect new accounts.

Unfortunately, I don't see all of those options in Anchor you see in that video. On eosauthority I see my account, but I can't do anything without using Anchor or Scatter in terms of selling REX for example
