Does anybody know the name of the icon that the launcher uses for missing items?



I'm not familiar with the code and I don't know where to look for it.
I'm been seeing throught the icons directory (just the PNG ones) but I don't find it.

Thanks in advance.

My system:
OS: Devuan 3.0 64 bits (based on Debian 10)
KDE Plasma 5.14.5
KDE Frameworks 5.54.0
Qt 5.11.3
Kernel 4.19.0
