Doctrine symfony multiple manytomany relations in one entity

I have Email entity with 3 manyToMany.

/**
 * @ORM\ManyToMany(targetEntity=EmailGroup::class, inversedBy="emails")
 * @ORM\JoinTable(name="email_to_email_group",
 *      joinColumns={@ORM\JoinColumn(name="email_group_id", referencedColumnName="id")},
 *      inverseJoinColumns={@ORM\JoinColumn(name="email_id", referencedColumnName="id")}
 * )
 */
private ?Collection $emailGroups;

/**
 * @ORM\ManyToMany(targetEntity=Department::class, inversedBy="emails")
 * @ORM\JoinTable(name="email_to_department",
 *      joinColumns={@ORM\JoinColumn(name="department_id", referencedColumnName="id")},
 *      inverseJoinColumns={@ORM\JoinColumn(name="email_id", referencedColumnName="id")}
 * )
 */
private ?Collection $departments;

/**
 * @ORM\ManyToMany(targetEntity=BranchOffice::class, inversedBy="emails")
 * @ORM\JoinTable(name="email_to_branch_office",
 *      joinColumns={@ORM\JoinColumn(name="branch_office_id", referencedColumnName="id")},
 *      inverseJoinColumns={@ORM\JoinColumn(name="email_id", referencedColumnName="id")}
 * )
 */
private ?Collection $branchOffices;

When I run php bin/console doctrine:schema:update --force I see this:

After it in database I have 3 tables with only one foreign key, but I thought that every table should only consist of foreign keys.

How to properly organize 3 many-to-many relationships in one entity? What am I doing wrong?
