A green banner will confirm the successful manger change.
The Second method, would be to change the manager through the employee file.

The Manager does not appear in the List?
If the manager you wish to assign the employee to does not appear in either manager change lists, the most likely cause is that they have have not been assigned to a manger level job role. Visit the Manager Level job role article for guidance on creating this role.
