I am not able to see the files in my hard drive

[Kobus]

I have installed Jellyfin on docker as a stack. And in the stack i told it to look for media under /media/myusername because that is where my external drives are mapped. But when i try to add a folder to my Jellyfin library, it shows that there is nothing in my hard drive. And it also looks like all the other directories have nothing in them. (I am very new to Jellyfin)
