Maybe the bug is in:

graasp-apps-query-client/src/hooks/postMessage.ts

Line 120 in 7ac0dda

window.parent.postMessage(JSON.stringify(data), '*');

According to: react-native-webview/react-native-webview#323 (comment)
We should not specify the targetOrigin (second argument).

The mobile app injects window.parent as window.ReactWebView since ReactWebView is the object on which you can call the postMessage that is received by the parent.
