/**
 * Returns an instance of `ConfigCatClient` for the specified SDK Key.
 * @remarks This method returns a single, shared instance per each distinct SDK Key.
 * That is, a new client object is created only when there is none available for the specified SDK Key.
 * Otherwise, the already created instance is returned (in which case the `pollingMode` and `options` arguments are ignored).
 * So, please keep in mind that when you make multiple calls to this method using the same SDK Key, you may end up with multiple references to the same client object.
 * @param sdkKey SDK Key to access the ConfigCat config.
 * @param pollingMode The polling mode to use.
 * @param options Options for the specified polling mode.
