mysql – How do I use sequelize npm package to access an existing table in a remote heroku cleardb database without defining its schema in my app

In the sequelize docs Im unable to find the suitable way to get a handle on a table in a remote database. Only way currently (as mentioned in the docs) to use the models ORM way of syntax to query or manipulate data in a remote database seems to be to first define its schema in my app itself and then persist it first to get a hold of it so that we can query the existing data. I basically do not want to use sequelize.models.query method and mention my sql query explicitly like

sequelize.models.query("SELECT * FROM <tablename>" )

and run it. But rather want to use the ORM methods of querying the data something like

await <table_name>.findAll({
        where: {
          userid: id
