Function is not creating inside Azure function App using ARM Template
I am trying to deploy the Azure Function App inside this one function using with Azure blob trigger using the ARM template.
I am able to deploy the function app and it's up and running but the function inside is not getting created.
First I created one function app and inside that create one function. I am copying all the files for that function in blob storage and providing the init.py and function.json file in appsetting

I want to create one function app with operating system as Linux and runtime as Python3.9 and inside that one function which can take the older function configuration and files from the blob storage.
I am able to create the function app shown below.
Now I want to create the function inside the function app shown below.
I tried to follow the documentation but I am not able to figure out how to create function inside the function app.
Solution
Function is not creating inside Azure function App using ARM Template: -
After a workaround on your requirement, I found an approach to add a function inside the function App using "Microsoft.Web/sites/functions" resource type as follows.
Code in ARM (Json) format:
