How to see the rest of the metadata in file view?

Title. I installed OneCommander almost a week ago and I really like it so far, but I do not understand how to see more metadata in any file view, custom or not.

I made a custom file view with ONLY metadata, because I thought there was not enough space, but no:

I feel very dumb because I must've missed something because this is a very basic thing to have in a file explorer.

How can I see the metadata of my files like I can in Windows Explorer?
