Opening larger models on mobile devices using APS viewer (Autodesk.MemoryLimited)

I have an Autodesk platform services application that uses the viewer.
I encountered a problem that I can’t load large models on iPad.
I tried solving the problem using Autodesk.MemoryLimited extension with limited success.
Is there any documentation for the extension? the only thing I can find was – This post

Using the extension in the suggested way:

const config = {
    loaderExtensions: { svf: 'Autodesk.MemoryLimited' },
    memory: {
        limit: 1024
    }
};

I was able to open the model on IPad pro 12 but not using Ipad 10.
I don’t even know what unit is the memory limit, guessing it is MBs I tried changing it to 150, after doing that I wasn’t able to open the model in any IPad and in desktop I was able to open the model but didn’t really see anything in the viewer.
I am able to open and see the model in BIM360 on IPad 10 so I am guessing it is possible.
Will appreciate any help with better documentation for the extension or an alternative way to open large models.
