How can I assign task to manager of employee's manager?

Content (required):

We need to configure 3 approval steps in a employee self assigned journey:

First step: approval by Employee's Manager (we have selected the line manager as performer)

Second step: approval by Manager of the Employee's Manger

Third step: approval by HR

How can we address the journey to the manager of the employee's manager?

Thank you

Francesca
