// The PinnedLauncherApps policy allows specifying three types of identifiers:
// Chrome App Ids, Android App package names, and Web App install URLs. This
// method returns the value that would have been used in the policy to pin an
// app with |app_id|.
//
// Web App Example:
// Admin installs a Web App using "https://foo.example" as the install URL.
// Chrome generates an app id based on the URL e.g. "abc123". Calling
// GetPolicyValueFromAppId() with "abc123" will return "https://foo.example",
// which is the value that would be specified in the PinnedLauncherApps policy
// to pin this Web App.
//
// Arc++ Example:
// Admin installs an Android App with package name "com.example.foo". Chrome
// generates an app id based on the package e.g. "123abc". Calling
// GetPolicyValueFromAppId() with "123abc" will return "com.example.foo", which
// is the value that would be specified in the PinnedLauncherApps policy to
// pin this Android App.
//
// Chrome App Example:
// Admin installs a Chrome App with "aaa111" as its app id. Calling
// GetPolicyValueFromAppId() with "aaa111" will return "aaa111", which is the
// value that would be specified in the PinnedLauncherApps policy to pin this
// Chrome App.
