If you have not set up your RokuTV, option 3 is easiest and more full-featured (voice control) , although option 2 should also work (likely without voice control). Cannot use option 1 to set up new device or a factory-reset device.
Can't use a Roku device or RokuTV without some sort of remote control in some form.
