Issue in getting created tokens by the specific address

GraphQL API
1 
query MyQuery {
  Solana(network: solana) {
    Instructions(
      where: {Transaction: {Signer: {is: "768PtBv5ynSPWfBFJVQzn9TJWaWVMLLj3Q73zzm16wqb"}}, Instruction: {Program: {Name: {}, Method: {is: "mintToChecked"}}}}
    ) {
      Transaction {
        Signer
        Signature
      }
      Instruction {
        Accounts {
          Address
        }
      }
    }
  }
}

I am trying to get the token mint instruction using the above query, but not working.
That account already minted one token in the following tx.

Can anyone check why its not working?

It seems that issue is caused because the API supports only 8h transaction information.
Is there any other way to get the 5 tokens created by specific address?
