How do I initialize the AWS SDK for Node.js to interact with Secrets Manager?

To initialize the AWS SDK for Node.js to interact with Secrets Manager, you'll first need to install the SDK and then import the `SecretsManagerClient` from the appropriate module. You can then create an instance of the client, optionally configuring region and credentials. For example: `const { SecretsManagerClient } = require('@aws-sdk/client-secrets-manager'); const client = new SecretsManagerClient({ region: 'your-aws-region' });`
