Metaquest 3 with vive trackers and IRL objects

Hi,

I am trying to add two vive tracker 3.0s to my unreal project (v 5.5) that was running fine with my Metaquest 3. I have been googling and reading forums, but I cannot seem to find a way (or a plugin combination) to have the active tracking from the trackers working along with the Metaquest HMD. I have to disable the MetaXR plugin to get the trackers to appear in LiveLink  (that have been set up in SteamVR) which means I can't preview in VR through the headset. It would be Ideal to transfer the calibrated locations (currently using Space Calibrator app) of the trackers to the starting point in the Unreal Engine so I can align the tracker on the irl objects, with the trackers attached to their digital doubles, correctly. 

My trials have also included using the -xrtrackingonly tag to start up the editor. 

Any assistance much appreciated.

Kind Regards,

Nathan.
