Display Button Controls Using Google Maps Javascript API v3

Question

So here is my problem: I am writing a web application using the Google Maps v3 web API. When scaling a building that shows the floor plan, the floor controls are not displayed, like on Android. Opening Google maps for Android and approaching one building, I get a control in the lower right part of the screen that shows the floors (B1, 1 and 2), and their selection shows that the floor. Not using the web API. At first, I thought that it could be as simple as indicating which controls were visible / added controls, but I don't come up with anything.

Does anyone else know how to make these buttons appear?

Note Even on the Google website (maps.google.com) in classic mode, these buttons do not appear when you zoom in on a building with a floor plan, so this may be a lost reason ...

Answer 1

I was asked to answer this question so that he did not sit in the queue that remained out of turn.

At the time this question was asked, Google Maps for the Internet did not support the floor cover buttons (as far as I know), so we switched to using our own SDK on Android and iOS.
