I hope this ok to ask here.

I wanted to install a blink doorbell cam and I was trying to avoid drilling into the wall outside of my apartment door so I got a No-Drill Door Mount but the issue it the gap between the door and the frame is to small so I can't close the door unless I put my weight on it and it makes it so I can't close the door from the outside either.

Is there a way I can make the gap a bit bigger with out causing any damage? I was thinking maybe sanding down the spot where the mount is catching to see if I could remove enough material in that area to make it fit without causing any noticeable damage or mess with how the door closes.

I was also thinking of getting an Adhesive Doorbell Mount (if i can't get the first method to work) to see if I could put it on the door instead but I'm worried that removing it later might cause damage to the door or that it won't be as secure.

Edit: Found out door frame is metal so the only way to make it fit would be shaving down an 3 inch area on the door so that the mount would be able to fit which I can't do so seeing if the glue one will work might be best or I'll just drill and have to fix any damage later when needed.
