need help with webkit_user_content_manager_register_script_message_handler_with_reply is not calling the callback function in javascript side.

[m182s]

using wpewebkit version 2.46.6

native side:
webkit_script_message_reply_return_value(reply, jsc_value_new_string(jsc_value_get_context(value), "Reply from native code"));
return false;

javascript side:

window.webkit.messageHandlers.NATIVECODE.postMessage(
"MessageFromJavascript",
(replyValue) => { console.log("MessageFromNative:", replyValue); //<<--- this one is not called
});

issue: javascript callback of the reply was not triggered or called.
Did I missed something?

I found out that I used the wrong usage. this doesn't trigger any callback but just a return value.
it should be:

result = await window.webkit.messageHandlers.NATIVECODE.postMessage("MessageFromJavascript");
