Is the Office 365 Activator CMD a Reliable Way to Activate Office 365?

I’m looking for a reliable way to activate my Office 365 subscription, and I found a method that uses the Office 365 Activator CMD. However, I’m a bit unsure about using command-line tools for activation. Has anyone here used this method to activate Office 365? Was it a smooth and successful process, or did you encounter any issues?

Here’s the link to the guide I found: https://productkeysbuzz.co/ms-office-365-activator-txt/. Does this method work for activation, or would you recommend using a different tool or method for activation?
