GMSCollisionBehaviorRequired (Default): Always display the marker
regardless of collision. This is the default behavior. Has no impact on
whether any other markers or basemap labels show.
GMSCollisionBehaviorOptionalAndHidesLowerPriority: Display the marker only
if it does not overlap with other markers. If two markers of this type would
overlap, the one with the higher zIndex is shown. If they have the same
zIndex, the one with the lower vertical screen position is shown.
GMSCollisionBehaviorRequiredAndHidesOptional: Always display the marker
regardless of collision, and hide any
GMSCollisionBehaviorOptionalAndHidesLowerPriority. Display the marker only
if it does not overlap with other markers. Does not
GMSCollisionBehaviorRequired. If two markers of this type would overlap,
the one with the higher zIndex is shown. Collision rules for markers with
the same zIndex are undefined.

Setting `collisionBehavior` in code allows customization of display logic. It's recommended to use the same behavior for all advanced markers.\n"]]
