Module not found when I require custom module from my github

Hi
I am following this doc https://www.espruino.com/Modules#espruino-modules
Created my github https://github.com/markmal/BangleApps/tree/master/modules/
I've put this into web IDE Module URL: https://github.com/markmal/BangleApps/tree/master/modules/|http://www.espruino.com/modules/

Also I tried direct link, but still getting the error

>require("https://github.com/markmal/BangleApps/blob/master/modules/AT6558.js");
Uncaught Error: Module https://github.com/markmal/BangleApps/tree/master/modules/AT6558.js not found
 at line 1 col 78
...e/master/modules/AT6558.js");

Also tried link that returns plain text

>require("https://raw.githubusercontent.com/markmal/BangleApps/master/modules/AT6558.js");
Uncaught Error: Module https://raw.githubusercontent.com/markmal/BangleApps/master/modules/AT6558.js not found
 at line 1 col 88
...s/master/modules/AT6558.js");

What am I doing wrong?
