How to parse the inner instructions of the transaction's instruction?

Question

Its parsing only transaction instructions, but not inner.

import { PublicKey, Connection, LAMPORTS_PER_SOL } from "@solana/web3.js";
import { SolanaParser } from "@debridge-finance/solana-transaction-parser";
import { RaydiumIDL } from "./idl/raydium.js";
import dotenv from "dotenv";

dotenv.config();

const rpcConnection = new Connection(process.env.SOLANA_RPC_ENDPOINT_2);

const txParser = new SolanaParser([{ idl: RaydiumIDL, programId: "CAMMCzo5YL8w4VFF8KVHrK22GGUsp5VTaW7grrKgrWqK" }]);

const parsed = await txParser.parseTransaction(
    rpcConnection,
    "3bSaEg71kkWDPtG94mn9bY8k2D7mABaqrQqL4F5JvzAEwukjqqwkjGhHBCb9fS5wVe1AG1J8i76ScKTZ59VGgJzt",
    false,
);

console.log(parsed);

const tokenSwapIx = parsed?.find((pix) => pix.name === "swap");

console.log(tokenSwapIx);

swap parsing output:

Example of what I want to get:

Answer 1

Off the top of my head but should be close enough:

for (const inner of tx.meta.innerInstructions) {
    for (const i of inner.instructions) {
        if (i.parsed.type === "transfer") {
            const amount = i.parsed.info.amount
            const source = i.parsed.info.source
            const destination  = i.parsed.info.destination
            const authority = i.parsed.info.authority
        }
    }
}

you'll also have to handle "transferChecked" in addition to transfer (it has slightly different structure for the amount, it adds an object with the decimals and amount}
