Webrtc connect peers on call function - socket.io

Question

I know this probaly is a longshot, but I was hoping for someone to point me in the right direction here.
I've made a simple peer to peer video connection, and wrapped it inside a function, so I can call it on a button click, but it's not running.
When it's not wrapped inside the "activateVideoStream" function, but just on load, it works fine. I have a feeling that the issue is around the async function, but I can't wrap my head around it.
Here is the code:
let isAlreadyCalling = false;
const remoteVideo = document.getElementById("remote-video");
const {
RTCPeerConnection,
RTCSessionDescription
} = window;
let peerConnection;
function activateVideoStream() {
const configuration = {
"iceServers": [{
"urls": "stun:stun.l.google.com:19302"
}]
};
console.log("Activate Video Stream");
peerConnection = new RTCPeerConnection(configuration);
navigator.getUserMedia({
video: true,
audio: true
},
stream => {
const localVideo = document.getElementById("local-video");
if (localVideo) {
localVideo.srcObject = stream;
}
stream.getTracks().forEach(track => peerConnection.addTrack(track, stream));
},
error => {
console.warn(error.message);
}
);
peerConnection.ontrack = function ({
streams: [stream]
}) {
if (remoteVideo) {
remoteVideo.srcObject = stream;
}
};
}
async function callUser(socketId) {
console.log("Call User");
remoteVideo.style.display = "block";
const offer = await peerConnection.createOffer();
await peerConnection.setLocalDescription(new RTCSessionDescription(offer));
socket.emit("callUser", {
offer,
to: socketId
});
}
socket.on("callMade", async data => {
console.log("Call made");
await peerConnection.setRemoteDescription(
new RTCSessionDescription(data.offer)
);
const answer = await peerConnection.createAnswer();
await peerConnection.setLocalDescription(new RTCSessionDescription(answer));
remoteVideo.style.display = "block";
socket.emit("makeAnswer", {
answer,
to: data.socket
});
});
socket.on("answerMade", async data => {
console.log("Answer made");
await peerConnection.setRemoteDescription(
new RTCSessionDescription(data.answer)
);
if (!isAlreadyCalling) {
callUser(data.socket);
isAlreadyCalling = true;
}
});
I've noticed that "peerConnection.connectionState" inside "callUser" is being set to "new", but without the function wrapped around, it's set to "complete", so that's probaly the issue.
