Type Alias PendingUsernames

PendingUsernames: StorageDescriptor<[Key: Binary], [SS58String, number, Enum<{
    Allocation: undefined;
    AuthorityDeposit: bigint;
    System: undefined;
}>], true, never>

Usernames that an authority has granted, but that the account controller has not confirmed that they want it. Used primarily in cases where the AccountId cannot provide a signature because they are a pure proxy, multisig, etc. In order to confirm it, they should call accept_username.

First tuple item is the account and second is the acceptance deadline.
