I can't backup my worlds

I moved the Minecraft storage to external storage, then I created a new world, and when I entered Android/Data from the phone from which I created the world, but I did not find the rest of the path. The "com.mojang.minecraftpe" is not found , I even tried moving the storage to internal storage and did not find a solution, so... Please fix it 🙏 . (I'm using "google translate" , So there may be spelling errors in the writing, I hope the speech is understandable)
