Is it possible to reassemble a gold frame with a mirror?

So i got a Canon EOS 2000D actually, but ifixit doesnt have this device. While i was cleaning my mirrors, two gold frames just fell out and a mirror. i left it and when i looked through the visier i saw that its the part where i can see normally. is it possible to reassemble it back on its place. I am not really into repairing stuff but maybe you guys will help. thanks
