Amazon Opensearch Serverless service does not show Dev/Test option while creating the cluster

Question

Hi I read in the documentation that there will be a dev/test option while creating AOSS cluster, but I do not see it, in either Easy option or Standard option. 
Can you please help me understand the reason behind it? 
I was thinking to keep my cost low while testing my service.

I have replicated internally and could observe that dev/test option is only available for OpenSearch managed clusters and not Serverless. However in OpenSearch Serverless for development and testing purposes, you can choose to disable redundancy while creating collection, which reduces the number of OCUs in your collection to two.

Please refer the below documentation which provides more information on the same, step 6 related to deployment type provides information regarding the redundancy setting.

The Dev/Test option for creating Amazon OpenSearch Service (AOSS) clusters may not appear due to regional availability, changes in the AWS Management Console interface, or account-specific limitations.

To manage costs while testing your service, consider using smaller instance types, utilizing AWS Free Tier resources if applicable, and implementing resource lifecycle policies for automatic deletion after testing.
