'How in Laravel run JavaScript code stored in php variable?

In the livewire component, I have the script tag:

<script>
{!! $script !!}
</script>

Let's say the $script variable contains console.log('test');

It is executed once - no surprise documentation explains this. The recommendation is to emit a custom event and listen to it, but the problem is that it does not work with code in a variable. In other words, this works:

<script>
    document.addEventListener('custom-event', () => {
        console.log('test');
    })
</script>

but this does not:

<script>
    document.addEventListener('custom-event', () => {
        {!! $script !!}
    })
</script>

Any idea how to solve this?
