Logitech LUA?

[Shadowr⁧⁧ritter]

Hello,
I try to create a script for my logitech mouse for Battlefield 4. So i want that the game activate the Lasersight when i shoot and deaktivate it when i stop (so when left mouse button is pressed then press "T" and after i release left mouse button it should press "T" again) but i tried everything and it doesnt work for me, do someone got a idea how to do it?
