Chrome remote Desktop Ctrl Alt Del

I am using Chrome Remote Desktop. The remote machine (Windows 7) is requiring CTRL+ALT+DEL to log in, but the command is not making it through. Is there a shortcut or menu to send a command?

You can use the options located in the sidebar (click on a small tab in the right side to open it). You can send special keys, like Ctrl+Alt+Del or Print Screen
