How to open the disc tray on my Lenovo T440p laptop if there's no button?

I can't find my disc tray when i go to "My PC". Its like the driver got uninstalled or something. Without that I can't open my disk tray.

Put your finger in the center of the closed tray draw, press in, then let go the draw it should open…

Now go to icon on screen right click on icon disc drive it should say eject try that ok

I've got an 80xg, it looks like there's a disk tray there but there's no button.
