Unreal Engine 5.0.3 Platform SDK

Hey, is there any place to access older versions of the Platform SDK for Unreal Engine 5?
We just released our VR title, Kid Pilot, to Steam and were beginning the setup to release it to the Meta Store. However, we're working with Unreal Engine 5.0.3, we do have the Meta XR plugin for this engine version, but not the Platform SDK, and on the downloads page, the oldest version is 56.0, for UE 5.2.1

Any help towards finding where the older versions of the SDK can be found would be greatly appreciated.
