HTTP request inside override GrabBegin not calling - oculusquest

Question

I override GrabBegin function and try to make a Post request whenever user grab an object. But it looks like the Request was never called. No error or warning issue from the condole. I also tried to print to console by using Debug.Log("Grab Begin") but it was never printed to the console. I am not sure what I am missing. I was still able to grab an object through the VR
public class AromaShooterGrabbable : OVRGrabbable
{
override public void GrabBegin(OVRGrabber hand, Collider grabPoint) {
base.GrabBegin(hand, grabPoint);
RestClient.Post<AromaShooterResponse>(url, new Post {
duration = 3000,
channel = 1,
intensity = 100
}).Then(response => {
Debug.Log(response.status);
}).Catch(error => {
Debug.Log(error.Message);
});
}
}

Answering my own question.
In AndroidManifest.OVRSubmission.xml add:
<manifest>
<uses-permission android:name="android.permission.INTERNET" />
<application
android:networkSecurityConfig="#network_sec_config"
>
</manifest>
In network_sec_config.xml add:
<domain-config cleartextTrafficPermitted="true">
<domain includeSubdomains="true">*</domain>
</domain-config>
<base-config cleartextTrafficPermitted="true"></base-config>
