Facebook 3D photos for the iPhone XR

So I recently purchased an iPhone EXR model and trying to use it to display 3D images through facebooks 3D photos feature. I’ve been having trouble getting this to work as the 3D photo option is Not showing up in their menu features. Some owners of the XR models are saying their getting this feature to work and others are saying it can’t work on XR model phones due to the fact the XR version only has one lens even though it has the portrait feature for photos. Which is correct?! Can XR iPhones use Facebooks 3D photo feature? Thank you in advance...
