Is it possible to redefine any key? For example: the "eject" key.

I can't capture a specific key in the app to redefine it. Is it possible to add this feature of capturing key events?

At this time, Multitouch is unable to remap the "eject" key due limitations in macOS and how Multitouch performs the remapping. I would guess that Karabiner would be able to remap it, which works in a different way than Multitouch.

Thanks.
Yes, Karabiner can do that.
I hope that I could replace the software with Multitouch which has similar functionality.
