TransactionInstruction authorizeWithSeed({ required Pubkey stakeAccount, required Pubkey authorityBase, required Pubkey? custodian, required Pubkey newAuthority, required StakeAuthorize authorityType, required String authoritySeed, required Pubkey authorityOwner, })

Authorize a key to manage stake or withdrawal with a derived key.

• [w] stakeAccount - Stake account to be updated.
• [s] authorityBase - Base key of stake or withdraw authority.
• [s] custodian - Lockup authority, if updating StakeAuthorize.withdrawer before lockup.
