Equivalent of { type: Schema.Types.ObjectId, ref:”myModel” } from mongoose in Sequelize. NodeJS

I need to write a model with help of Sequelize, but I can’t find an equivalent of Schema.Types.ObjectId, ref:”myModel” there. How I can implement this one? I’m new in this technology and in DataBases.

I’m trying to get an User Id from another model and put to this one when creating. It’ ll help me to implement JWT token model.
