Prevent drag on first or last slide

[iforcode]

I config my slides like
<vueper-slides :infinite="false" :dragging-distance="70" :disable-arrows-on-edges="true">
It's good but I think vueper-slides has option to prevent drag to right on first slide and drag to left on last slide thanks.
This is my example https://codepen.io/iforcode/pen/RwVKqgZ
And when I drag to right on first slide, it still dragging and you will see a large white space, how to prevent that thank.
