CfnMessageTemplateVersion

Creates a new Amazon Q in Connect message template version from the current content and configuration of a message template. Versions are immutable and monotonically increasing. Once a version is created, you can reference a specific version of the message template by passing in `<messageTemplateArn>:<versionNumber>` as the message template identifier. An error is displayed if the supplied `messageTemplateContentSha256` is different from the `messageTemplateContentSha256` of the message template with `$LATEST` qualifier. If multiple `CreateMessageTemplateVersion` requests are made while the message template remains the same, only the first invocation creates a new version and the succeeding requests will return the same response as the first invocation.
