How to get list of permissions in a role

I'm using Romanbican/Roles laravel package, and I have permission_role table, roles table, and permissions table. Now, I want to get all permissions of a specific role. e.g. (role: Admin, permissions: create.users, delete.users, edit.users. The result would be:

Admin:

• create.users
• delete.users
• edit.users

how can I do that? Here's my tables with fields:

roles

---

id | name | slug | level |

---

permissions

---

id | name | slug |

---

permission_role

---

id | permission_id | role_id |

---
