Using iCloud Notes on a Windows PC

Hello!

I use an iPhone, but I'm still a Windows PC user when it comes to my computer use.

I'm looking to make a switch to iCloud Notes as my main note-taking app. However, I find that the user experience is limited on my Windows PC. I can't seem to lock notes. Whereas, on my iPhone, I am able to lock notes. Am I missing something? Why can't I lock notes on my PC, but can lock them on my phone? I don't want to write notes in my PC and then have to lock them using my phone. I'll look to a different app if that's the unfortunate case.

Thanks!
