Proposal: JS Module that Implements Fee Delegation Transaction Mechanism

[PaulElisha]

Description

• A Javascript Module that implements Fee Delegation Transaction Mechanism using Caver-js to call functions such as: signTransaction and sendTransaction for usage in Frontend Applications. A Klaytn developer can run this in a full frontend application to ensure the handling of gas fees payment is abstracted and in a single click.

Ok. Here are some requirements:

• React. So if you can turn that into a hook or just a util function are ok.
• Include a simple react app with any frameworks of your choice. I only need the necessary components to demonstrate the action described above.
• No need for styling even. But i want you to focus on UX, ie. my experience when i use the frontend application (not UI which is fancy design, we don't need that here). basically careful handling of states and easy to understand flow.

Anyway, approved to proceed. Revert back here with repo github link and deployed frontend app (use any deployer you like, cloudflare, vercel, etc.)
