How to stop a running 1password ssh agent?

I was experimenting with the 1Password SSH agent and clicked on the "Set Up SSH Agent..." button. However, I couldn't find a way to undo my selection.

In my opinion, there should be an option to easily cancel, reverse, or reset the settings back to their defaults in case I make changes that I'm unsure about, especially when dealing with unfamiliar settings.

I attempted to uninstall 1Password and reinstall it, hoping that it would revert the changes, but unfortunately, that didn't work.
