Razer Nari Essential - Repalcement Ear Cushion

Hello everyone, My wife bought a Razer Nari Essential a year before covid. She's very happy with the product. However, one of the ear cushions started to fall apart, up to a point where the gel is leaking out. I'd like to know where I can get replacement cushions, as I didn't find anything on razers replacement-parts site that seems to be explicitly compatible with a Nari headset. Can someone point me into the right direction? Thank you in advance.
