There is no Notification Channels creation resource in 2.x.x versions, but there is in 1.0.0

Is your feature request related to a problem?

While we create monitor we need to assign a notification channel. Since we want to implement all the related configs via terraform we don't want to create additional objects inside a cluster manually, but there is no ability with provider version >= 2.0.0

What solution would you like?

Develop a resource which creates a Notification Channel

What alternatives have you considered?

Develop a datasource which provides us headers for making an own http-request via terraform/http provider. This would be an awesome solution to implement it for making any http requests to our clusters and would be nice if both, main and alternative solutions, are implemented

Do you have any additional context?

[kolesaev]

My bad. I found it called opensearch_channel_configuration. Testing

Upd.
You should fix documentation for opensearch_monitor as there is opensearch_destination.slack_on_call_channel.id in the example

And would be nice if we have a datasource which prepares headers to simple http requests via terraform/http provider or via curl.
