Its nothing special, just a generic supersaw (most likely 3xOsc). If you understand the basics of a supersaw, then keep tweaking things to try and find the exact sound.
The only things I will add is that firstly, this supersaw sounds like it has a white noise top layer to give it some hiss. It's also very bright, so maybe EQ sweeping around the top end to see if a simple spike helps give you the sound.
