+    1) Alternatively, set the proxy on the device itself, which the app honours through `DefaultProxyProvider`, and which also works on a physical device:
+       ```
+       adb shell settings put global http_proxy 10.0.2.2:8080
+       ```
+       Use `adb shell settings delete global http_proxy` to remove it afterwards. On a physical device, replace `10.0.2.2` with the address of the machine running mitmproxy.
 1) Install the mitmproxy CA cert (this is needed to see traffic from java/kotlin code, it's not needed for traffic coming from native code e.g. the matrix-rust-sdk).
     1) Open the emulator Chrome browser app
     1) Go to the url `mitm.it`
     1) Follow the instructions to install the CA cert on Android devices.

 1) Slightly modify the Element X app source code.
-    1) Go to the `RustMatrixClientFactory.create()` method.
+    1) Go to the `RustMatrixClientFactory.getBaseClientBuilder()` method, which builds every client the app creates, whether it is logging in or restoring a session.
     1) Add `.disableSslVerification()` in the `ClientBuilder` method chain.
 1) Build and run the Element X app. 
 1) Enjoy, you will see all the traffic in mitmproxy's web interface.
