I'm using vercel, and when I set the preview URL to the VERCEL_URL environment variable, it will point to the underlying deployment url instead of the branch URL.
The urls look like this
branch URL: projectname-git-dev-orgname.vercel.app
deployment URL: projectname-xyz123-orgname.vercel.app
If I access the admin panel from the branch URL, live preview will not work, but works fine if I use the underlying branch URL.
Is there any way for me to specify for the deployment URL (which is always specific to the code running in the backend) to work regardless of the URL that's hosting the admin panel (which essentially proxies the underlying url)?
