Anonymous user access issue when trying to read SpList with CSOM in SharePoint 2013

Below is the ps script that needs to be executed (WebApplication setting) to enable anonymous Users to access SpLists using Client side object Model.

$webapp = Get-SPWebApplication "webAppurl"

$webapp.ClientCallableSettings.AnonymousRestrictedTypes.Remove([microsoft.sharepoint.splist], "GetItems")

$webapp.Update()
