Signs a Gnosis Safe multisend transaction that approves the Trading Credits (TC) token and Conditional Tokens for trading. It returns a `TokenApprovalResponse`containing the signature and transaction payload to submit, or `undefined`if approval is already sufficient.

```typescript
import { ForkastSDK, Network } from "@forkastgg/client";
import { Wallet } from "ethers";

const sdk = new ForkastSDK(Network.MAINNET, "YOUR_API_KEY");
const accountService = sdk.getAccountService();

const signer = new Wallet("YOUR_PRIVATE_KEY");

const approval = await accountService.approveMaxPlatformCreditsForProxyWallet(
  signer,
  "YOUR_PROXY_WALLET_ADDRESS",
  10_000_000 // optional buyAmount
);

if (!approval) {
  console.log("Already approved");
} else {
  console.log("Signature:", approval.signature);
  console.log("Payload:", approval.dataSign);
}
```

**Parameters**

| **Field** | **Type** | **Required** | **Description** |
| ------------------ | -------- | ------------ | ------------------------------- |
| signer             | string   | Yes          | Public address of the wallet    |
| walletProxyAddress | string   | Yes          | Trading wallet address created  |
| buyAmount          | number   | No           | Amount of tokens to approve     |

<Info>
  The signer must be the `owner`wallet of the proxy, and should have a provider attached (the SDK will attach one if missing). Use the returned `TokenApprovalResponse` payload in your transaction submission flow.
</Info>

<Warning>
  `buyAmount`is optional. If omitted, the SDK uses `MAX_BUY_AMOUNT = 10_000_000` and approves the maximum amount.
</Warning>
