💡 [TransactionRequestInput] - Request input is missing the ability to specify some fields required for dapps

[darrenvechain]

Summary

When specifying the TransactionRequestInput, users should be able to specify:

• A comment, describing the transaction
• A delegation URL, to delegate the transaction

Basic Example

const signer = new VeChainAbstractSigner(...)

const tx = await signer.sendTransaction({ comment: "Hello", delegationURL: "https://example.com"})
