Hello :)
I'm part of the team that created this component.
I just looked into it and have a solution. In the end all you'll need to do is to add the CSS class sidebar-left on the component, like this:

The class definition is as follows:
.sidebar.sidebar-left {
right: inherit;
left: 0;
-webkit-transform: translateX(-102%);
transform: translateX(-102%);
}
.sidebar.sidebar-left.sidebar-open {
-webkit-transform: none;
transform: none;
-webkit-transition: all 330ms ease-out;
transition: all 330ms ease-out;
will-change: transform;
}
You can add it on your theme to use it right away if you want here:
However I also published a new version of the component with this extra CSS already on it. So if you want you can just update the component on your environment and add the new CSS class :)
Let me know if you need more help,
José
