deploy opensearch with cognito auth without manual intervention (terraform)

Hi,

ive created a terraform module to deploy aws opensearch with cognito auth.

Then problem is that when creating the aws opensearch it needs the cognito user pool and identity pool. To create the idenity pool, i need to create a dummy client app. and when opensearch is created it creates a new client app. That is not added to identity pool mappings.

Is there any way around this? Is it a terraform problem or a cognito / opensearch problem / or finishes crossed a me problem!
