Read appsettings.json from a class in .NET Core 2

I need to read a list of properties from appsettings.json file (section: placeto) in a business class, but I haven't been able to access them. I need these properties to be public.

I add the file in the Program class:

Class program

This is my appsettings.json:

{
  "Logging": {
    "IncludeScopes": false,
    "LogLevel": {
      "Default": "Warning"
    }
  },
  "placeto": {
    "login": "fsdfsdfsfddfdfdfdf",
    "trankey": "sdfsdfsdfsdfsdf"
  }
}
