Pass a parameter to a store's read method while using autoLoad

I'm a novice with extjs. I have a ViewModel which autoLoads a store. However, I need to pass a parameter to my Read method in the store's api. How would I go about doing that in the below scenario? I tried to put paramOrder on the proxy but that didn't work.

ViewModel:

Code:

Ext.define('Rsvp.Web.grid.DelegateViewModel', {
    extend: 'Ext.app.ViewModel',
    alias: 'viewmodel.delegate',

    stores: {
        delegateStore: {
            type: 'delegateList',
            autoLoad: true,
        }
    }
});

Store:

Code:

Ext.define('Rsvp.Web.store.DelegateList', {    extend: 'Ext.data.Store',
    storeId: 'delegates',
    requires: [
            'Rsvp.Web.model.Delegate'
    ],
    model: 'Rsvp.Web.model.Delegate',
    alias: 'store.delegateList',
    proxy: {
        api: {
            read: 'Direct.SessionOrganizer.GetDelegatesBySession',
            create: 'Direct.SessionOrganizer.InsertDelegate',
            destroy: 'Direct.SessionOrganizer.RemoveDelegate'
        },
        writer: {
            writeAllFields: true,
            encode: false
        }
    }
});
