find Material on fab that is visible in quixel

HI, so on Quixel i can easily find a Surface for example named Limestone. U can even search in quixel for the word limestone and get loads of results. Now in Fab i cant seem to find any of these. I did claimed al megascans. But allot of surfaces i just cant seem to find on fab, i asume that al assets from quixel should be available also on fab. i thought searching on AssetID but also that doesnt work. i added some screenshots.

Can somebody please help me how i can or should search for specific surfaces that i see/find on quixel, on FAB.


@BySaliano those assets are not available on Fab yet.
Also, please note some assets have been deprecated and will not be coming over to Fab at all.
