I see; it is a box cage trap - Havahart. I was curious how to not 'manually' open the door... according to the video you have to be at the opposite end of the trap from the trap door and manually pull up on the handle. I agree that with that sort of release it would be helpful to have a cover on the trap so the trapped animal only sees an open exit, not the 'trapper' - until it has run free.
Humane trapping is good, but the release can be perilous - especially with larger animal traps. Wild cats and bears may want to wreak some revenge on their captors; skunks I don't know, never trapped those. 🤔 I have caught possums once or twice and just opened the door for them to back out; they aren't really aggressive.
