Problem reopening the code edit window

Hello everyone, I would love your help.

I’m working on creating an experiment, I manage to add images for example and change the details about them - when I double-click on the image icon, the options open for me (editing the image name, placing the image on the computer, etc.). This is also true for other functions.
However, for some reason, after I add a code, when I double-click on its icon, the window with the details of the code and its editing option does not pop up again. Anyone know how I can solve this problem?

Many thanks in advance.
