What is the correct way to resolve this error on a toast (popup notification)? eg name? aria-labelledby? Is the to describe what is in the notification or what the component is?

What is the correct way to resolve this error on a toast (popup notification)? eg name? aria-labelledby? Is the to describe what is in the notification or what the component is?

I'm using https://bootstrap-vue.org/docs/components/toast

This renders something like this

<div role="alert" aria-live="assertive" aria-atomic="true">
    <div tabindex="0">
        <button type="button" aria-label="Close">×</button>
        <div>
            <p>Some notification text</p>
        </div>
    </div>
</div>
