MyComponent.svelte

onMount(() => {
    postElementId = crypto.randomUUID();
    ...
});

Error

TypeError: crypto.randomUUID is not a function

I've got a component that uses the crypto api to create a random id and works as intended, but when I want to test it, everytime I do this error pops up, any help is appreciated!
