Special icons on lock screen?

I would like to have (on Android) on my Huawei honor 8x mobile phone at the lock screen some quick access icons, like camera, phone, etc.

Does anyone know the right attitude or an app?

I do not think so

Yes, but if I install different themes, there's sometimes a camera icon at the bottom right.

Unfortunately, this is only possible with Samsung Galaxy devices. At Huawei, unfortunately not.
