Which category is the Any.Button.Click block in?

[NoIdea]

I saw a screenshot of it in a post and searched every category in Mit App Inventor for the block but couldn't find it. (Link: No procedure possible when using "Any Button.Click"?)

Does anyone know if you need to drag something to the phone in the designer view or install an extension in order to use that block?

Scroll the palette on the left down to the bottom when in the blocks editor, you will find the AnyComponents blocks there

You have to drag in at least one non generic Button first.

The any component tree is in the blocks editor pallet below the non generic component tree.

Alternatively, take a Button1 block and right click it to make it generic.

Thanks!
