CALDAV requests over Cloudfront not working

I'm serving Nextcloud in an EC2 instance via Cloudfront to internet. All seems to work fine, except when I try to connect to my calendar via CALDAV. This is the error message I get: This distribution is not configured to allow the HTTP request method that was used for this request. The distribution supports only cachable requests.

My behaviour is currently configured with CachingDisabled as Cache policy and AllViewer as Origin request policy.

Allowed HTTP methods are set as GET, HEAD, OPTIONS, PUT, POST, PATCH, DELETE.

It seems I need to add Request Method PROPFIND in this somehow, but this doesn't seem to be supported by Cloudfront. Is there another way?
