You can't "reask" when the user has denied access from it.
What you can do however is to monitor when they will change this setting, by listening to the PermissionStatus.onchange event (that is in Chromium based browsers, Firefox still doesn't support the camera value).

So you'd do:

// after you caught denial
const status = await navigator.permissions.query({name: "camera"});
status.addEventListener("change", (evt) => {
  // request again
  navigator.mediaDevices.getUserMedia({ video: true })
    .then(handleStream)
    .catch(handleDeny);
}, { once: true });

You can't (as this could lead to permission prompt spam).

The user will have to reset or change this in the browser settings. You'll need to guide them to that when getting a NotAllowedError from getUserMedia (it is a rather complex process) or you explain the process carefully in advance, avoiding the "deny" click most of the time.
