Best solution ever: Cut the original plastic retainer prong. Trim flat. Use a temperature controlled soldering iron to insert an M4 hot melt knurled insert. Set the temperature to 250⁰C. Keep on side a water sprayer full of water and tested for proper spaying. Melt the insert using as little vertical force as possible in the position of the prong you cut. When the plastic gives in, prepare to spray water. When the insert is flat with the surface, spray plenty of water on it to cool it. Use an M4 black Torx screw to attach the lanyard.
