Updating a Svelte store value onMount doesn't work

In one of my Svelte components, I'm trying to reset the count value in the store to 0 upon mounting the component.

Here's how I'm attempting to do it:

<script>    import { onMount } from "svelte";    import { writable } from 'svelte/store';    const myStore = writable({      count: 1    });    function updateCount() {    $myStore.count = 0;    console.log("my store:", $myStore);  }  onMount(() => {    updateCount();    console.log("my store on mount:", $myStore); // count will be 1  });</script><!-- count is 1 --><h1>{$myStore.count}</h1>

However, upon rendering the component, I notice that the count value remains 1 instead of being updated to 0 as intended. Even though the updateCount() function is called inside the onMount hook, the console logs inside the hook show that the count is not updated.

For now to fix it I have it like this:

onMount(() => {    setTimeout(() => {      updateCount();    }, 1);  });

Thank you for your help!
