Plugin installed but no option can be found to debug

[nvwebm]

Hi, I installed the plugin, but I can't debug my app
I'm using ionic 4

I put this in config.xml:

 <config-file parent="/manifest/application" target="AndroidManifest.xml">
            <meta-data android:name="WebViewDebug" android:value="true" />
</config-file>

installed the plugin as said in documentation build for release but I can't see my app on emulator on chrome://inspect
