External monitor cant change refresh rate on macbook air m2

Hey, so I have macbook air m2 and I have this ultrawide monitor from xiaomi, 32 inch curved with VA panel (Xiaomi Curved Gaming Monitor G34WQi - Xiaomi UK), I am trying to change its refreshh rate, but its stuck on 50hz, however the monitor supports 180 on my other laptop and PC, what could be the cause? I am using hdmi 2.1 cable, and a usb c to hdmi dock
