Global Mapper v24.1

Remove small polygons merging them with the outer polygon


I am working with some sample data from the official training of Global Mapper, and I am trying to do a vectorization of a raster, but after I use the tool "Create area features from Equal Values", but I am getting some isolated pixels (image below) so I am wondering if there is a tool for removing those little polygons by merging them to the bigger outer polygon.

In this case those little polygons could be replaced just by the green background which is a more representative area. I know that in the GIS world there are some processes that can achieve this, I just wonder what the process is in Global Mapper.
