Replacement Keyboard Membrane?

My girlfriend has a Chuwi Hi13 (Cwi534) and she spilled some juice on the keyboard, ruining it.

I disassembled it and managed to pinpoint the problem to the keyboard membrane - the circuit board is working perfectly.

I’ve seen replacement entire lower half of the laptop, but they’re a bit expensive.

Is there a replacement keyboard membrane I can buy?

Thank you and best regards!
