Installation error employee_check_list (employee_documents_expiry is not available)

[mjrk]

On install of employee_check_list, odoo version 16.0, we receive "User Error: You try to install module 'employee_check_list' that depends on module 'employee_documents_expiry'. But the latter module is not available in your system."

In manifest we find in the depends employee_documents_expiry, but this module is not available in Odoo CE or this repository. There is a module oh_employee_documents_expiry, but if I change the depends-entry to it, installation will fail (different model names)

Possibly, we need to use this module from a different repository: https://github.com/CybroOdoo/CybroAddons #

However, this is not documented and might be wrong, too.

How should we proceed?
