Unable to delete Foundry Agent identity Entra app in Azure

I'm trying to delete an Entra app in Azure created by Foundry Agent identity blueprint as its currently unused and is causing EntraID hygiene alerts. However getting an error mentioning that delete is not supported. 

Is there any other way to delete an unused Entra app for an agent identity blueprint?

Error detail: Agent Blueprints are not supported on the API version used in this request.
