Material design toolbar – Margin left on title when no icon

In the material design guidelines I can't find how much should the left margin be for the title, when there is no "nav icon" (as it is called in guideline).

We see here:

https://material.io/guidelines/layout/structure.html#structure-app-bar

There is always a nav icon, the three stripe menu icon. When this is present we have a margin left of 72dp.

How about when it is not present?

Is there a better guideline with more detailed margins/padding for material guidelines? Stuff is missing like the above case, and the dimensions of icons, and font size, elevation, etc.
