Hi,
I configured a lockdown for Samsung tablets.
Right now it looks like this

I want to have the "Icons" without the white "background". How can I edit this so it is transparent?
Also: Under "Horsch", the icon doesn't get shown, although I marked an Icon as active and also it doesn't open a browser. I used: browsers://htmllink
