Can I mount a Video Doorbell 3 Plus without screws?

Morning all, Wonder if someone can help me as i am new to Ring products. I have purchased a Ring Doorbell 3 Plus and would ideally like to attach it on my metal front door, so dont want to use Screws to attach it. If i put it on the wall beside the door then it wont have the best view due to the angle of it. Can someone suggest an alternative way to attach it to the door that is sturdy and wont fall off? Thanks in advance.
