Desktop support

[omarzer0]

At first thx for your awesome libraries and great effort.

I'm using Biometry Auth in my KMP app and worked fine until I added Desktop support. I get this error

No matching variant of dev.icerock.moko:biometry-compose:0.4.0 was found. The consumer was configured to find a library for use during compile-time, preferably optimized for standard JVMs, as well as attribute 'org.jetbrains.kotlin.platform.type' with value 'jvm' but:
          - Variant 'debugApiElements-published' capability dev.icerock.moko:biometry-compose:0.4.0 declares a library for use during compile-time:
              - Incompatible because this component declares a component, as well as attribute 'org.jetbrains.kotlin.platform.type' with value 'androidJvm' and the consumer needed a component, as well as attribute 'org.jetbrains.kotlin.platform.type' with value 'jvm'

I know that Desktop has no touch or face ID but is there a way to exclude JVM targets from using this library or we can provide a custom auth screen for Desktop with pin number or even let the user provides his own implementation for it when isBiometricAvailable returns false?

@omarzer0 were you able to solve this issue, I mean were you able to use moko-biometry while supporting desktop app?

Any update on this issue? tried to work around for many hours but ending up with "@composable invocations can only happen from the context of a @composable function" no matter what I do, either I support desktop app or biometry, not a great choice either way.

interface BiometryAuthenticator {
    suspend fun checkBiometryAuthentication(
        requestTitle: String,
        requestReason: String,
        failureButtonText: String,
        allowDeviceCredentials: Boolean
    ): Boolean
}

I was able to solve this issue with this work around. https://stackoverflow.com/questions/78659556/composable-invocations-can-only-happen-from-the-context-of-a-composable-functi/78665157#78665157b
