Toggle Modes using Alexa

Thanks for the reply, but I do not have Ring Alarm. The links you provided are how to do all of that with Ring Alarm. Modes can be operated with just the security cams, doorbell cameras, etc… without having Ring alarm. I have created many Alexa routines using the Ring Skill for motion detection, etc… What I want to do is change the mode of the Ring System (not alarm) using Alexa. When you create a routine, you must specify an action against something, usually with a smart home device, but to change the mode of the Ring system it cannot be a camera, it has to be a central/common thing such as Ring Alarm System. So, without that, how can the Ring system be addressed to change the mode via Alexa routine or verbally via Alexa command?
