How can I add a backdrop to my toast

Hello,

I want to display an "Are you sure?" toast to my users that they can't skip. I tried using a modal or backdrop, but it requires manual styling because the modal takes up the entire page, and my text is aligned to the left. I've shared an image to show this.

Lastly, is there a way to remove the closing delay when I call closeToast? There's a noticeable delay before the toast disappears.

Thank you!
