useMapsLibrary vs google.maps.drawing

[mladen-at-endurosat]

After migrating to react-google-maps, can one continue to access the API and libraries via google.maps or one should always use useMapsLibrary?

for example:

// NEW WAY
import { useMapsLibrary } from '@vis.gl/react-google-maps'

const drawingLibrary = useMapsLibrary('drawing')
const isMarker = drawingMode === drawingLibrary?.OverlayType.MARKER

vs

// OLD WAY
const isMarker = drawingMode === google.maps.drawing.OverlayType.MARKER

How should one handle these API imports:

1. interfaces, types like MapProps
2. constants, enums, like OverlayType
3. methods, classes like LatLng

When I use the OLD WAY after the migration, from time to time I get google.maps.drawing as undefined even if I followed the instructions for loading the API.
