How do I disable express logs in my node.js CLI?

I am new to node.js and I am trying to move away from using console.log for debugging everything. I am trying to use

debug("test message")

instead of console.log for everything.

I installed the debug npm package, and it instructed me to:

The app message in blue is the only relevant message to me since I am trying to use that instead of console.log. How can I get rid of these express logs? Do you think at some point they would be important?
