How do you request the DynamoDB.DocumentClient service in a plugin?

To make AWS requests in a plugin, you can do something like this:

  constructor(serverless, options) {
    ...
    this.provider = serverless.getProvider('aws');
  }
	...
  hook() {
  	...
	await this.provider.request('S3', 'put', params);
  }

How do you request DynamoDB.DocumentClient?

Looking at awsProvider.js, it seems like there is no way to do so. If so, are there any workarounds?

This is now supported in Serverless 1.59.0: https://github.com/serverless/serverless/releases/tag/v1.59.0 (code change: https://github.com/serverless/serverless/pull/7031)
