Allow custom colors for 'element focus' to be set when embedding

Clicking the report surface within an embedded application renders a blue outline, highlighting the element in focus. Whilst this is important for accessibility reasons, it would be great if the color of this could be modified by passing in a color preference within the embedded configuration object.

In some cases, the outline can clash with either the host application style - or the report content, making the outline unusable as an assistive tool -> being able to change the color would allow developers to maintain a good level of contrast whilst also enabling the ability to keep the color 'on brand'.

CSS example from embedded playground markup:
.embedWrapper:focus {
outline: 1px solid #51cbee !important;
}
