did you import fbx or glb file ? 
 i recommend using glb files since gltf can be imported easily on unreal 

go to your plugins , and enable GLTF IMPORTER , should be in built plugin :)

edit: no need no enable anything  it's already enabled , just drag in it :)

also I recommend to enable the combine static mesh when importing for some objects like for example the keyboard which have parented objects in it , but since unreal don't parent them automaticaly u will to parent it manualy, so if you enable combine static mesh it will merge it to one object, i don't know if there's a option to importing with the childs objects, if you know something guys pls tell me hahhaahhahha
