How to make the sequelize object global in the project?

Question

Express.js

Hello.

I'm doing a rest api on express and I want to somehow globally access sequelize.
Project structure

• Controllers/
  
• Middlewares/
  
• Services/
  
• Models/
  
• app.ts
  

The sequelize object is created in app.ts.
I need to get this object in models from the Models folder for initialization using the model extension
