Is the ncw js sdk not supported in react native? I’m getting: `ReferenceError: Property 'document' doesn't exist, js engine: hermes` Implying that the sdk is trying to use `document`, why is this? isn’t the sdk supposed to just handle js logic? why is it trying to access the DOM? ---

Are there any workarounds for using the sdks in react native? ---

Hello @roberthq I have followed up with my team and Fireblocks ncw js SDK currently does not support React Native, but we by the end of this Q1, we will come out with React Native Support. We still have an iOS Swift SDK and fully functioning NCW [demo](https://github.com/fireblocks/ncw-ios-demo) written in Swift, also and android example written in Kotlin [GitHub - fireblocks/android-ncw-demo](https://github.com/fireblocks/android-ncw-demo) There is still plenty more you can do with the ncw-js-sdk without using react! ---
