For internal usage whe have a list view action on our case list views.
In our experience Site we have a page "Case list View". On this page is a list view of all cases. There are no List Action visible. This is great. But when I switch to mobile view. One List Action appears. We do not want that List Action on the experience site. I have not found any set up to make the action invisible.
I attached a screenshot from the Builder where you see that the action is not checked to be shown.
