I have a Samsung S21 Android phone.    When entering contacts into the phone directly, there is no option to save them to Zoho contacts, is there a way to do that?   The same applies for calendar entries.   I want Zoho Contacts and Calendar to be my primary source of contacts and calendar entries.

I have browsed the forum and came across CardDAV, but I cannot locate that in the play store, it's not there.

ps. I did send the above directly to support via email, so sorry if duplicating.
