GTK accelerator for "Entry" key?

Platform

I’m trying to set the following accelerator shortcut:

ShortcutsWindow help_overlay {
  ShortcutsSection {
    section-name: "shortcuts";

    ShortcutsGroup {
      title: "General";

      ShortcutsShortcut {
        title: "Send message";
        accelerator: "<Control>Enter";
      }
    }
  }
}

But I’m getting the error:

Gtk-WARNING **: 22:33:24.154: Failed to parse <Control>Enter, part of accelerator '<Control>Enter'

I’ve also tried <Control><Enter>, but doesn’t work.

The examples only provides examples with pretty simple keys, but none shows how to set the Enter key.

The key is called Return, not Enter, according to this table gdk/gdkkeysyms.h · main · GNOME / gtk · GitLab

So the accelerator would be <Control>Return
