Accessible Wordpress plugin for pop up alerts

Good morning,
Can anyone give me a recommendation for an accessible WordPress plugin that will allow me to display a pop up? I need to be able to alert users about system maintenance occasionally.

I found this one, but it’s not quite right. I can tab through the page behind it before it traps the focus.

Many thanks,
Jessica
