Retrieve a Signature for Listing:
Use the createSignatureToListNFTForSale API to generate the necessary signature to authorize the listing of the NFT. This ensures that the marketplace has permission to list the NFT on behalf of the user.
Execute the Listing Transaction on the Frontend:
After obtaining the signature, the frontend application should execute the listing transaction on the Solana blockchain. This step involves:

Creating a listing account for the NFT.
Transferring custody or escrow of the NFT to the marketplace, if required.
Specifying the sale price and conditions.

Ensure the transaction is confirmed on the blockchain.

Confirm the Listing Submission:
After the transaction is successfully executed, use the submitProofOfApproval API to notify the marketplace that the NFT has been listed and approved for sale. This step involves:

Submitting proof of the blockchain transaction.
