Inserting data to multiple columns at once

Issue Description

Hello! I'm building CRUD based on express/ typescript / graphql and I have a problem with inserting data to few tables at same time .

I have three tables

Posts m:n -> Songs m:n -> Artists I also have two intermediate tables .

I'm trying to create it like this:

Posts.create({
                    userId: user.id,
                    ...data,
                },{
                  logging: console.log,
                  include: [{
                      model:Songs,
                      include: [{model: Artists , as: 'artists'}]
                  }]
                })

                return null
            } catch (err) {

                throw err;
            }

First include works and songs with posts are created in proper way. Artists is empty and I don't receive anny error
