Access secure file on Azure DevOps from pipeline when signing Android apk

Question

How to access .jks file stored in "Azure Secure Files" from "Azure Pipelines" while signing Android apk?

My idea is just to call gradlew assembleRelease to generate and sign apk on Azure Pipeline. Signing in gradle is configured like this:

    signingConfigs {
    register("release") {
        storeFile(file(System.getenv("APK_KEYSTORE")))
        storePassword(System.getenv("APK_KEYSTORE_PASSWORD"))
        keyAlias(System.getenv("APK_KEY_ALIAS"))
        keyPassword(System.getenv("APK_KEY_PASSWORD"))
    }
}

Can't access the APK_KEYSTORE file stored in "secured files" in Azure

What I've already tried and it works is this Android signing task, but I need signing and generating apk locally also, so I need this one example above
