Question: how to set to show multiple action items, taking as much as possible?

[AndroidDeveloperLB]

I can see on the screenshots of the material guidelines that it's possible to show more than just 2:

How do I do that? I can even see that there is a way to set the action items on the left (and hopefully still have the overflow item on the far-right-edge) :

Is it possible only for BottomAppBar, or for Toolbar in general?

Please show in the sample how to do both.

I even wrote a question about this here, because initially I thought it's something of the Toolbar itself.
