I want to use hermes on react native.

android/app/build.gradle

  project.ext.react = [
      entryFile: "index.js",
-     enableHermes: false  // clean and rebuild if changing
+     enableHermes: true  // clean and rebuild if changing
  ]

Added in proguard-rules.pro

-keep class com.facebook.hermes.unicode.** { *; }
-keep class com.facebook.jni.** { *; }

$ cd android && ./gradlew clean

Done above things still when I log it, it shows false.

console.log("isHermes", !!global.HermesInternal)

What should I do in this?
