How to get one object if the table is connecting(ManyToMany)?

Question

symfony

Hello everyone, I have a question. I have 3 tables with a ManyToMany relationship. Tables Page, Role, PageAccess. The PageAccess linking table has the fields role_id, page_id, visible. The role_id and page_id fields are a composite primary key. When I select one page from the Page table with a query, I would like to have a method in which, for example, I could pass $role_id and get one PageAccess object as a result. How can I do that? Is it necessary to somehow describe the OneToOne relationship in the Page table? Or is it just a way to write something?
