accessible frame options

I think the simplicity of this plugin is great, but my use of this plugin hinges on the ability to make the embedded iframe accessible; currently it’s failing- https://dequeuniversity.com/rules/axe/4.11/frame-title?application=AxeChrome. If the shortcode could offer ‘aria-label=”Site Name/description”‘ and/or ‘title=”Site Name/description”‘, that would make the embed accessible.

Thanks for considering the importance of this issue.
