Hi Schiarla,

Thanks for writing back to us.

Please try inputting this css:

#slide-out-widget-area:not(.fullscreen-alt):not(.fullscreen), #slide-out-widget-area-bg.fullscreen, #slide-out-widget-area-bg.fullscreen-split, #slide-out-widget-area-bg.fullscreen-inline-images .nectar-ocm-image-wrap-outer, #slide-out-widget-area-bg.fullscreen-alt .bg-inner, body.material #slide-out-widget-area-bg.slide-out-from-right {
    background-color: #ff49117d;
}

If this fails to work, then please send us your website URL so that we can provide css for it.

Thanks.

Hey Again,

I am afraid this is not possible at the moment without customizing the underlying JS files. However have noted it in the Wishlist for upcoming updates. 

Best
