solana - 可替代资产最大供应量？

Question

有谁知道我如何为 Metaplex 可替代资产添加最大供应量？

  const metadata = await Metadata.getPDA(mint.publicKey);
  
  const createMetadataTx = new CreateMetadataV2(
    { feePayer: mint_authority.publicKey },
    {
      metadata,
      metadataData: new DataV2({
        uri :'https://xxxx-88-81-106-161.ngrok.io/sample-uri',
        name: 'ttt',
        symbol: 'ttt',
        sellerFeeBasisPoints: 100,
        creators: null,
        collection: null,
        uses: null,
        tokenStandard: TokenStandard.Fungible
      }),
      updateAuthority: mint_authority.publicKey,
      mint: mint.publicKey,
      mintAuthority: mint_authority.publicKey,
    },
  );

  const sig = await connection.sendTransaction(createMetadataTx, [mint_authority],{
    skipPreflight: false,
  } )
    
  const txRpcResponse = await connection.confirmTransaction(sig)
