Does anyone know a working addon which can do this? Sound is no priority.
I believe this to be a simple request, but after googling, chatgpting and other attempts, neither VNC nor any other connecting service seems to be able to do this.
Maybe someone knows something that I do not 
Thanks!
Sorry but this is not supported. LE/Kodi does not support being "casted" to and the VNC add-on that can be installed only allows remote viewing of the LE/Kodi "desktop" not the reverse. The open-source world rather sucks at this stuff; largely because all the devices that (most) users want to cast from are controlled by corporations that only show love for their own captive/walled-garden device ecosystems.
