Show confirm popup while deleting file from 'Delete' button

I have just installed "Deepin 20" and it is running fine. Now issue is that when I delete a file by pressing a Delete button then it deletes file immediately. If I delete it with shift+delete then it shows confirmation but it delete it permanently. I just want that it should show a confirmation popup then it should proceed and not delete permanently. I have tried to place alias rm='rm –I' in ~/.bashrc but it does not work. If there is a solution for this then kindly provide it.
