Views slider for remote video w/ thumbnail nav

I read through the VIEWS.md file but it doesn't describe this situation.

I was able to get another slider working with remote video thumbnails using the field formatter, but that won't work for this one. I'm unable to select a thumbnail or main stage for the slider.

Should I be using the Splide Grouping format?

I got this working.

Set up the view with Splide Slider as the formatter, using fields.

Add the remote video field, formatted as blazy media, using image to media as the media switcher <-- This part is essential.

Add the remote video field again, formatted as thumbnail.

Set these as the main stage and thumbnails in the splide formatter settings.

Create an option set and nav option set as needed.
