Unable to ADD assets inside Unreal Engine 5.5.0

This only works for larger asset packs. Not for individual meshes or the many materials I have added to my library over the months. So far I only see a clumsy process of individually downloading them, unzipping, then dragging into my open project which more than half the time requires me to completely reset each material and figure out where to attach all the textures. It is insanely time consuming and I keep thinking that there must be a better way. It feels like the whole community is reeling from Epic recently breaking a very helpful QuixelBridge feature and not replacing its functionality at all. If anybody does know the best practice to incorporate several materials or even meshes that come with materials, please chime in. I keep searching and getting totally different (mostly outdated) advice. Thanks!
