Azure custom resource provider long running resource creation

Question

I need to create a custom resource provider with an Azure function in the backend. So my ARM template would look something like this - https://github.com/Azure/azure-quickstart-templates/blob/master/101-custom-rp-with-function/azuredeploy.json

I am confused about how I must design this Azure function. I want to understand how a resource of custom resource type is provisioned through ARM template.

When the custom resource is provisioned through ARM template, is a POST request made and response of the API would determine if the provisioning succeeded or failed?

If so how can I put a long running operation here? Can my POST call give a response after 1.5 hours of processing?

Or in custom resource provisioning through ARM template, would POST call be made followed by GET calls till the GET call returns 200 OK?
