// Creates a channel to which you can add users and send messages. Restriction:
// You can't change a channel's privacy. The x-amz-chime-bearer request header is
// mandatory. Use the AppInstanceUserArn of the user that makes the API call as
// the value in the header. This API is is no longer supported and will not be
// updated. We recommend using the latest version, CreateChannel (https://docs.aws.amazon.com/chime-sdk/latest/APIReference/API_messaging-chime_CreateChannel.html)
// , in the Amazon Chime SDK. Using the latest version requires migrating to a
// dedicated namespace. For more information, refer to Migrating from the Amazon
// Chime namespace (https://docs.aws.amazon.com/chime-sdk/latest/dg/migrate-from-chm-namespace.html)
// in the Amazon Chime SDK Developer Guide.

// Deprecated: Replaced by CreateChannel in the Amazon Chime SDK Messaging
