  data: Buffer.from(
    'AAAAAAbFwc5jjSVn0mRosF65UdGijcxuEjSCtcZ1FJdw5ivyEyZQoUCNAwAGAQAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA==',
    'base64'
  )
}

const account = borsh.decode(accountInfo.data, ['accounts', 'Mint'])
/* => {
  mintAuthorityOption: 0,
  mintAuthority: 'TSLvdd1pWpHVjahSpsvCXUbgwsL3JAcvokwaKt1eokM',
  supply: 999733653939731n,
  decimals: 6,
  isInitialized: true,
  freezeAuthorityOption: 0,
