WebDAV share: how to mount on CLI with access to non-priviledgs user and no /etc/fstab?

I have never used WebDAV before (I like sshf) but I am trying it. I want to mount a remote WebDAV share that I set up on my server, on my local computer.

If I try as non-priv user I can't access mount command fully.

If I try as root I can't access the folder as user. I used this command: sudo mount -t davfs -o noexec https://nextcloud.example.com/remote.php/webdav/ /mnt/dav/

I don't want to use /etc/fstab because I don't want the share to be mounted before I establish a VPN (but I do want mount -a in rc.local)

Is there something like -o idmap=user I can use for WebDAV?

Using Linux obviously.
