Junior using chatgpt only

How to teach my junior who only relies on chatgpt. They will not look into documentation/IDE suggestions to understand what they are copying.

I am concerned that in this way, they aren't going to learn about the entire system and grow to work independently. How data flows in the system and where to look into if something is wrong.

Basically, they are not trying to understand the code they are writing. How do I bring this to them and explain that they need to use less chatgpt to actually understand what they are supposed to do or are going to write. Once they have that experience, I am fine with them using chatGPT as much as they want to.
