Server world download

So I tried downloading the world from my server (Minecraft Bedrock 1.16.0.2 android) because I also wanted to play on the world offline. Once I downloaded the world, I extracted the zip file on games/com.mojang/minecraftWorlds/ and created a new file so that I can put the extracted files in the new file. I opened Minecraft, changed the file storage location to external and the "world" world that I downloaded from the server is there but when I entered the world, I came back to the old world spawn point and I don't have anything on my inventory. It looked like that my world was reset but it didn't look like that on my server. Is there anything/anyone that can help me download the exact same world from the server so that I can play on the world online and offline?
