Azure spring cloud redis association parameters

Hello, I am trying to create a Azure Spring Cloud association to an Azure Redis instance with terraform. There’s an option for a spring_cloud_app_id and spring_cloud_service_id. I’m confused because is the app_id the specific id for an application. If so won’t that mean I can only associate one app per redis instance. And what is the service_id meant to be, is it the Spring Cloud resource ID?
resource "azurerm_spring_cloud_app_redis_association" "example" {
name = "example-bind"
spring_cloud_app_id =
redis_cache_id =
redis_access_key = azurerm_redis_cache.example.primary_access_key
ssl_enabled = true
