activityModeHash property
The hash identifier of the most specific Activity Mode under which this activity is played. This is useful for situations where the activity in question is - for instance - a PVP map, but it's not clear what mode the PVP map is being played under. If it's a playlist, this will be less specific: but hopefully useful in some way.
Implementation
@JsonKey(name:'activityModeHash')
int? activityModeHash;
