I think for now we can follow the existing 4844 example and do

 let sidecar = sidecar.build()?;

    // Build a transaction to send the sidecar from Alice to Bob.
    // The `from` field is automatically filled to the first signer's address (Alice).
    let tx = TransactionRequest::default().with_to(bob).with_blob_sidecar(sidecar);

provider.fill(tx).await.unwrap();

// and then convert the tx into the 7594 variant

this isnt super pretty but will do the job I believe


// TODO: Build a transaction to send the sidecar from Alice to Bob. I'm not sure how to create this tx atm, researching...

// Send the transaction and wait for the broadcast.
let pending_tx = provider.send_raw_transaction(tx).await?;

println!("Pending transaction... {}", pending_tx.tx_hash());

// Wait for the transaction to be included and get the receipt.
let receipt = pending_tx.get_receipt().await?;

println!(
"Transaction included in block {}",
receipt.block_number.expect("Failed to get block number")
);

assert_eq!(receipt.from, alice);
assert_eq!(receipt.to, Some(bob));

Ok(())
}
