Reading NfcV in App Inventor

Background
Hi, I have recently received an project to read NfcV tag with text message via an app. An example app has been given that successfully read the corresponding data. I have tried to use either the App Inventor Near Field or the MifareInfo extension but no luck. I have then tried to use NFC TagInfo by NXP and found that the tag is an NfcV tag. Further investigation with Google and Android Studio found that there should have a library(?) in classes.dex->android->nfc->tech->NfcV in order to read NfcV tag. However, I do not have the knowledge of editing completed/compiled apk files that I could copy the NfcV library from the example app.

Aid Required
I would like to know if App Inventor have extension for reading NfcV tags, or suggestions on copying the NfcV library from the example app to my App Inventor app.

Thanks in advance!
