Azure Policy for enabling diagnostic settings for WebApp/Function App - No resources remediated

Question

I am working in an existing Azure environment where there is no governance and I am in the process of creating Azure Policies. Currently I am working on creating Azure Policy to enable Diagnostic settings for Azure Web App, Azure Function App and Web API. Initially I had one Azure Policy for all type of Web Apps. Later I split into two.

1. Web App & Web API
2. Function App

I thought to address the Function App with the below Policy Rule. But no resources where remediated.

We have about 60+ web apps without any governance and now when I want to implement Diagnostic settings to most of the azure services I find it difficult to debug why the azure policies are not remediated. Because when you remediate a policy it tries to perform the DeployIfNotExists action for azure web apps which is not an efficient way. How do we validate the policy rule conditions from a Cloud engineer point of view? Use Kusto Queries or Powershell/Azure CLI on the policyrule.

I tried with the built-in policy for function app (Enable logging by category group for Function App (microsoft.web/sites) to Log Analytics) but it didnt work as well.
