Any assets migrated from a UE 5.4 project to 5.3.2 do not appear in the 5.3.2 version of the project.

Unless this has change, you can’t add a .uasset created on a higher version engine to a lower version, you should have get some error msg in the output log, something like outdated version.
If you are just transfering some mesh, exporting as fbx might do the trick.
