How do I set the background on the Huawei p30 Lite?

I have a Huawei p30 Lite. There's the Magazine function on the lock screen. Automatically changing background images are displayed, whereby you can also add your own. But how can I get the pictures from Huawei preset in the magazine so that I only see my own pictures in turn?

Disable all subscriptions and delete the downloaded ones and insert yours.
