iCloud password request

Hi,
I’m a tumbleweed user an last week I’ve updated my disks, recovered the /home from the previous system and reinstalled a brand new SO. After the login this modal pops up and I don’t know where it come from as there is no application name in the title.
I thought was probably due to some previous configuration related to Kmail, but I removed all my accounts there as I’m using thunderbird, but still appears.
Any suggestions where to check?
Thanks.

Edit: probably the culprit is akonadi but not sure how to remove this request.

At the end I removed the akonadi configuration and restarted akonadi:

sudo akonadictl stop

rm -rf ~/.config/akonadi*
rm -rf ~/.local/share/akonadi

sudo akonadictl start

It solved the issues, no more modal.
