how to disable visibility of an object in timeline?

[lda.com]

If I add one object starting from anywhere after zero, its showing me a visible icon in timeline and by adding key frames I can make it invisible.

but same option not showing for objects starting at zero

How do I make them invisible after a particular frame?

there are two ways:
- go to the frame you want, open the layer proprieties, uncheck "visible"
- go to the frame you want, now, in the layer window, click the triangle at the right side of the layer name and uncheck "visible"
