Hi, I already used the Cloud Anchors sample in ARCore SDK download from unity website, but I want to use the Cloud Anchors through the ARCore plugin downloaded from package manager. The ARSession in Sample is different from the package manager and website download, the setting in website download is have SessionConfig and CameraConfigFilter. My project use the package from package manager, but the "GoogleARCore" libs cannot be found, and it shows "Using directive is unnecessary." How can I use the Cloud Anchors? Thanks.
