Trigger a component function on svelte store method

Question

I have a svelte store with a method called 'right'. When right is triggered I want the function handleNextImage in my component file to run. I am unsure how to do this properly, thanks!

import { writable, get } from 'svelte/store';


const createMyStore = () => {
    const store = writable({
        Rows: [],
    });

    const { subscribe } = store;

    return {
        subscribe,
        right: (cb: (msg) => void) =>
            update((x) => {
             ....
            return x;
            }),
    };
};


export const myStore = createMyStore();

COMPONENT.SVELTE

import { myStore } from '@screens/home/myStore';

myStore.right(() => {
        console.log('go right in store');
        handleNextImage()

    });

const handleNextImage = () => {
        does a thing...
    };
