For example, I have anappointments model and apatient model. Theappointment model has apatientId. Is there a way to define the types so that:

appointment.findByPk(appointmentId, {include: [{model: db.patient}]});

results in a return type that includes the patient object on it? And vice-versa, if I don't include thepatient model, can I get a return type where the patient object is not defined? I have the associations defined with decorators on theappointment class but it seems to always assume thatpatient will be present on theappointment object.
