How to use 'qscc/GetBlockByHash' in peer CLI and Java gateway?

I failed to use qscc/GetBlockByHash on the Java gateway and peer CLI, and I couldn't find any relevant information on the network. But I can use 'blockchain explorer' to retrieve the correct information.

Hi, you cannot send the hash string directly. You need to decode it into bytes representing the hexadecimal, cast it to string and send it. Something like this:

String blockHash = "your_hex_string_here";  // Replace with your actual hex string
byte[] hashBytes = HexFormat.of().parseHex(blockHash);

Let me know whether you are able to get the block by hash that way. I am interested in this because I am running into problems with the same function, as outlined in #5003.
