  3. navigate to chain state
  4. select balances
  5. select total issuance
  6. if you want to know the total issuance at a specific block height, pass the block hash to the blockhash to query at field, e.g. I checked the block 10000000 hash 0x6c51377632106ddba379416f2ef5e24450e90cee8c78a70daa262b2ae6f27e93
