How You Enable Managers to Manage Their Succession Plans
Your organization might want to allow some managers to create and manage their own succession plans.

So, you need to create a custom role with a different security profile that allows managers to manage their own succession plans. You then need to assign this custom role to managers in addition to their predefined Line Manager role.
