Error reading Schema Registry Clusters when environment is created in the same step

After upgrading to Terraform provider version 2.*.0 where schema registry cluster resource is removed, schema registry cluster data source read fails when read is deferred to the apply phase.

Terraform Confluent provider: 2.0.0 and higher Terraform version: 1.9.7

Terraform setup:

module "confluent_environment" {
 ...
}

module "schema_registry" {
  ...

  confluent_environment_id = module.confluent_environment.confluent_environment_id

  ...
}

¨ This works fine only in a setup where the environment already exists and we swapped the schema registry cluster resource for data source following the Confluent Provider 2.0.0: Upgrade Guide.

Issue is encountered when trying to deploy an environment and read the data source in the same plan/apply sequence. The same result is obtained both with an implicit dependency and when using the depends_on block.

Plan output:

# module.schema_registry.data.confluent_schema_registry_cluster.schema_registry will be read during apply
  # (config refers to values not yet known)
 <= data "confluent_schema_registry_cluster" "schema_registry" {
      + api_version   = (known after apply)
      + cloud         = (known after apply)
      + display_name  = (known after apply)
      + id            = (known after apply)
      + kind          = (known after apply)
      + package       = (known after apply)
      + region        = (known after apply)
      + resource_name = (known after apply)
      + rest_endpoint = (known after apply)

      + environment {
          + id = (known after apply)
        }
    }

Expected behaviour: Data source is read once the environment is created, and the apply step completes successfully.

Actual behaviour: Apply step fails with error: Error: error reading Schema Registry Clusters: there are no SR clusters in "env-***" environment

Workaround: Introducing 5 seconds delay between environment creation and data source read with time_sleep resource results in a successful apply phase.

Is it possible to introduce this delay in the data source itself such that using the time_sleep resource is not necessary for this setup to work?
