Appwrite Fucntion req.get('authorization') Not Working

Hello guys, from the api docuation of livekit.io https://docs.livekit.io/realtime/server/webhooks/#Receiving-webhooks, it is stated that to recieve webhook the `req.get('authorization') will need to be called, but calling it in Appwrite Cloud function its outputting

    at Module.default (file:///usr/local/server/src/function/src/main.js:29:48)
    at execute (/usr/local/server/src/server.js:157:48)
    at async action (/usr/local/server/src/server.js:174:13)
    at async /usr/local/server/src/server.js:10:9```

 How can this be resolved?

The request object in Appwrite Functions is slightly different to what would normally be expected in Express, this might give a clearer idea as to what you're looking for https://appwrite.io/docs/products/functions/develop#request

It looks like it's trying to get the value of the authorization header which I think is done like this

const authorization = req.headers["Authorization"];

I'm not sure if that's 100% correct as I'm trying to do it from memory but the link I sent will give a much better idea as to what you need to be doing
