How to add contract to existing employee

Summary:

Content (please ensure you mask any confidential information)

Hello everyone,

we are encountering a problem regarding migrant employees/collaborators in the system, in particular we have noticed that there are some of them as screenshots below to which no contract has been associated with the assignment.

Could you help us understand how we can add a contract to such employees, also via UI or if there is the possibility of doing so without having to delete and migrate the case again.

many thanks for your availability

Regards,
Gerardo
