No CalDav option showing with Calendar plugin? Shows on cPanel, though.

[new-to-this]

Hello,

I have been trying to create a RoundCube installation that mimics the default cPanel installation as closely as possible.  I have nearly accomplished everything except for one confusing and frustrating issue: the option to add a new calendar gives no option for a CalDAV URL or authentication.

I am attaching two images.  The first image compares the enabled plugins and the version.  You can see that the cPanel version is 1.4.8 and the version I have installed is 1.4.9.  Similarly, you can see that the only plugins I do not have activated are the cPanel proprietary plugins used for their login screen, etc.

The second image shows what I see when I click on the "Add Calendar" option.  You can see that the cPanel installation shows an option to include a CalDAV URL as well as authentication, but my installation does not.

Any ideas on how I could fix this?

Thanks!

I think that they are using https://github.com/texxasrulez/caldav_calendar since it doesn't have a package.xml it wont show up in that plugin list.

Well, I just installed and enabled that to try it out and had no change to the interface or options.  Also, I got a site admin at my host to give me a copy of the cPanel RoundCube plugins folder and here is the list of all the plugins included in the directory:
 acl
 additional_message_headers
 archive
 attachment_reminder
 autologon
 calendar
 carddav
 cpanellogin
 cpanellogout
 database_attachments
 debug_logger
 emoticons
 enigma
 example_addressbook
 filesystem_attachments
 help
 hide_blockquote
 http_authentication
 identicon
 identity_select
 jqueryui
 krb_authentication
 libcalendaring
 libkolab
 managesieve
 markasjunk
 new_user_dialog
 new_user_identity
 newmail_notifier
 password
 redundant_attachments
 return_to_webmail
 show_additional_headers
 squirrelmail_usercopy
 subscriptions_option
 userinfo
 vcard_attachments
 virtuser_file
 virtuser_query
 zipdownload

Not sure if that helps, but I can't get access to any calendar at this time.
