Replace FN/Left-Click with ⌥-Right-Click

Hi there!

Essentially, I'd like to trigger left-click/FN with ⌥-Right-Click when hovering over a link but am failing.

Here's the background...
I use an app called Velja that presents users with different browser options for opening a link. This is particularly useful for links I want to open in Chrome apps. It has a native shortcut of FN-Left Click to present the browser selection prompt. However, I would like to change this shortcut, which is awkward. I tried a few ways but failed. Any suggestions?
