Redwood - Make descriptive flexfield in Skills and Qualification visible only to specific roles

Hello experts,

We are facing an issue in the migration to Redwood interface for skills and qualification since in NUX some customization had been made in order to make some Flexfield visible only to specific roles and not to all the employee.

We notice that in visual builder we cannot work an the section but on the template and, moreover, it is not possible to act on the flexfield in order to limit the visibility of fields to specific roles.

Do you know if there is a way to make the fields visible conditionally on the roles? Have you experienced similar problems?
