Custom relation table Symfony 4 and Doctrine

I need help to solve some task about Doctrine Relation Table.

I have two entities:

PropertyGroup

• ID
• Name

Property

• ID
• Name

This entities have a custom Many To Many relation table with extra column

PropertyAndGroupRel

• ID
• PropertyGroupId
• PropertyId
• SortKey

How can I select PropertyGroup with QueryBuilder or NativeQuery with using LIMIT and OFFSET in this view:

{  { // PropertyGroup    id: 1,    name: 'XXX',    properties: { // Properties Collection      {        id: 11,        sortKey: 1 // SORT KEY FROM PROPERTY_AND_GROUP_REL,        name: 'XXX'      },      ...    }  }  ...}

Thanks in advance!)
