ThirdWeb ERC721 Gasless Relayering and Webhook Script

I am trying to create a gasless minting dApp using ThirdWeb's ERC721 NFT Drop contract. I followed this guide:

I am struggling this part:

  1. Create an Autotask in the Dashboard under Autotask.
  • Name: your desired name for the Autotask.
  • Trigger: set to Webhook
  • Connect to a relayer: Select the Relayer you just created.
  • Code: Remove the autofilled code, copy the code from our GitHub and paste it in the Code box.

The following code is outdated since on the webhook, it says:
We are migrating our packages to @openzeppelin/defender-sdk, we recommend you to migrate your Action code imports if you haven't. They are not available anymore in any dependency version after v2024-01-18

:computer: Environment
I am using OpenZeppelin Defender's Relayer and AutoTask Webhook.
