A toggle to select whether folder view or document view the default in the client portal docs area

During a client meeting I’ve just discovered that folders I set up in a client’s document library aren’t replicated in their view. I thought I was setting up folders and subfolders to help them find advice reports amongst all the T&Cs, KIIDs etc we have to provide.

It turns out that all they see is a pages of individual files without a folder structure. I see that there is the ‘show in folder’ option for each file but it isn’t obvious to click this.

Can there be a way to show the folder structure by default?
