Use a 5.3 UE level in UE 5.0

Hi guys.
I have bought a level (link) and I can launch it via 5.3 but for some reason I have to use it in 5.0 so migrate this level completely to my content folder in 5.0 project. but when I open 5.0 project there is not any asset. I can see the folder of level and maps but without any asset (materials, texture, object ,…) also I can see uasset files in file explorer. how can I fix it?
