Default to thumbnails when sharing photos

I use Nextcloud to delivery photos to clients. The shared folder defaults to the Listing configuration rather than Thumbnails. I would like the shared folder to initially display thumbnails. Is there a way of doing this? It’s not always obvious to clients that they have to click on the four square in the top left hand corner to view thumbnail images. Or maybe this graphic could be replaced by or include the words “View Thumbnails”.
