Grant acess to folder application pool (ASP.NET MVC)

Question

I have app on Azure App services

In project wwwroot I have uploads folder.

I need to grant it full control read permission

I connect to website using IIS Manager

Here is screen

And have application pool settings

But I don't understand how I can give permissions to folder

Help me please

UPDATE

I go to this folders and check permissions

Full control is on

Answer 1

Edit permissions again and try to add Machine\\Users and IUSRS. Verify Authentication configuration is the desired for your site (For example Anonimous Auth + Edit -> AppPoolIdentity)
