Assign Mac globe key as mouse left click with double click and drag feature

I am trying to assigning the letter 'globe key/ fn key' on my keyboard to perform as a left mouse button, including the actions left-click, double-click and hold/drag.
But it is not working i tried copy pasting the solution provided in similar topic but it only works if i assign this to another key on keyboard like "q" etc but it does not work with globe key.
plz help
PS: I tried and mapped my globe key as backslash key and then assigned backslash key to the mouse click. Now it is working properly except double click is not working.

The solution which was provided on the forum which i used is this:

{
  "BTTTriggerClass" : "BTTTriggerTypeKeyboardShortcut",
  "BTTPredefinedActionType" : 119,
  "BTTPredefinedActionName" : "More Mouse Buttons & Modifiers(⌃⌥⇧⌘) \/ Custom Click",
  "BTTCustomClickConfig" : "100(null)",
  "BTTCustomClickUpDownConfig" : "1",
  "BTTAdditionalConfiguration" : "0",
  "BTTEnabled2" : 1,
  "BTTUUID" : "08B5A93D-7F72-484E-AB06-7CD546FAA47E",
  "BTTTriggerOnDown" : 1,
  "BTTEnabled" : 1,
  "BTTShortcutKeyCode" : 12,
  "BTTShortcutModifierKeys" : 0,
  "BTTOrder" : 15
}
{
  "BTTTriggerClass" : "BTTTriggerTypeKeyboardShortcut",
  "BTTPredefinedActionType" : 119,
  "BTTPredefinedActionName" : "More Mouse Buttons & Modifiers(⌃⌥⇧⌘) \/ Custom Click",
  "BTTCustomClickConfig" : "100(null)",
  "BTTCustomClickUpDownConfig" : "2",
  "BTTAdditionalConfiguration" : "0",
  "BTTEnabled2" : 1,
  "BTTUUID" : "9A18334E-A718-47B5-A775-02F4755138EA",
  "BTTTriggerOnDown" : 0,
  "BTTEnabled" : 1,
  "BTTShortcutKeyCode" : 12,
  "BTTShortcutModifierKeys" : 0,
  "BTTOrder" : 16
}

You can use this, however make sure to 4.682 alpha because I have just added the ability to do double-clicks like this:
