Cannot see the Clock-Object in Screen list

MIT App Inventor Help

I want to use the clock object. But it is not displayed. What should I do?

2

It is a "Non-visible component"

Hello Juan_Antonio,
I'm in the process of creating an APP as an example after a tutorial. Clock is used in this APP and assigned to an object.
See How to Make a Fidget Spinner App with Android App Inventor 2 - Full Tutorial - YouTube
and there from minute 17:20.
There the object clock is visible in the screen list at Canvas. I want to do that again. But not possible. I don't have Clock in the screen list.

What am I doing wrong?
Thanks very much.

In the Designer, open the Sensors component Pallette, and pull in a Clock component.

It should appear below the layout pane.

I have now dragged the clock element from the "Palette" onto the mobile phone in the "Viewer". Now it is suddenly displayed under the mobile phone in the "Viewer" as a non-visible component and is available with its command blocks.
Unfortunately I couldn't find that anywhere. I couldn't find this link with google either.
Thank you ULLI
