Does vehicleCostmap this type of map only support pathPlannerRRT object to plan a path? Can I use another algorithm to plan a path?

I really dont know how to use A* algorithm in vehicleCostmap this type of map to finish the path planning.
there's plannerAStarGrid method in Navigation toolbox, unfortunately, which are not allow to use in vehicleCostmap.
so, the question is that vehicleCostmap this type of map only support pathPlannerRRT object to plan a path? Can I use another algorithm to plan a path in vehicleCostmap?

Currently, plannerAStarGrid only supports binaryOccupancyMap and occupancyMap.
Alternatively, you can convert your vehicleCostmap object to occupancyMap using the following syntax:
p = vehicleCostmapObj.Costmap;
resolution = 1/vehicleCostmapObj.CellSize;
map = occupancyMap(p,resolution);
map.FreeThreshold = p.FreeThreshold;
map.OccupiedThreshold = p.OccupiedThreshold;
and then pass it to plannerAStarGrid.
