I tried finding something similar, but it doesn't look like there was a way. I just refunded it on Play Store and bought it here once I got my refund, since there's an Android APK download available on this page anyway.
In Discord there's a chanel where it states that the only way to have 2 versions it's buying the PC version and redeem it on Google play store, but no the other way around.
I did manage a workaround by downloading an Android emulator and playing my Android version on it, so there's that if it helps anybody.
