### Overview

**This endpoint is deprecated.** Test if permissions are present to add a log-forwarding triggers for the given services and AWS account. The input
is the same as for Enable an AWS service log collection. Subsequent requests will always repeat the above, so this
endpoint can be polled intermittently instead of blocking.

- Returns a status of 'created' when it's checking if the Lambda exists in the account.
- Returns a status of 'waiting' while checking.
- Returns a status of 'checked and ok' if the Lambda exists.
- Returns a status of 'error' if the Lambda does not exist.

This endpoint requires the `aws_configuration_read` permission.

### Request
