P: Web Gallery with a Slide Show & Exporting Larger Images to WebP or preferably AVIF

It would be VERY nice and HELPFUL is Adobe Lightroom Classic exported Web Galleries included WebP and AVIF image formats.  Also, if the web gallery added this behavior...  When you click on a thumbnail and the larger (preferably WebP or AVIF) image appeared, there was a slideshow button so it would cycle through all the Web Gallery (again, preferably WebP or AVIF format) images.  This would provide our customers with a Slide Show experience where they can sit back and enjoy the Web Gallery content.

If I am in error, please let me know what I need to do the accomplish this.

Thank you,
