Uploading files (Steam Deck)

[Valtharr]

So, yesterday, Discord decided to stop working on my Steam Deck for some reason. Just keeps loading and not doing anything. So, I shopped around for alternative clients, found WebCord, and was happy with it. But then, just now, I tried uploading a file and it didn't work. Drag and Drop brings up an error message, and clicking the "Upload File" button brings up a file explorer that... doesn't actually show me my files? It's a bit hard to explain, but it doesn't show all the folders on my Deck, including my microSD, where I have most of my files. But even when I tried copying the file to a folder the explorer (supposedly) shows me, I couldn't find it.
