Change color of lands and waters in geobasemap

I see that we can "Edit a predefined style — Editing a predefined style is available for vector basemaps added from MBTiles files".

However, how can I modify the colors used for land and water? For example, the current map shows land in green and water in light blue, but I would like to customize these colors. How can I access and change the exact color values?

mbtilesFilename = "naturalearth.mbtiles";
if ~isfile(mbtilesFilename)
    mbtilesFullPath = fullfile(matlabroot,"toolbox","map","mapdata",mbtilesFilename);
    copyfile(mbtilesFullPath)
end
basemapName4 = "bluegreenstyle";
addCustomBasemap(basemapName4,"naturalearth.mbtiles",Style="bluegreen")
geobasemap(basemapName4)

If you have the JSON file (as shown in the example above the one you linked), you can directly edit the "fill-color" property in layers like "land", "ocean", etc. to use the hex color you prefer.
