How can I label multiple routes on a geoscatter plot?

I am generating multiple route plots using geoscatter. Each plot has its own color but I would like to label each of the plots as well. Below is the code I am using to generate the plots from various gpx files. I appreciate any suggestions for how this can be done.

fig = figure;
pos = fig.Position;

files = dir('cast*.gpx');
for i = 1:length(files)
    filename = files(i).name;
    route = gpxread(filename);
    geoscatter(route.Latitude, route.Longitude, 50, "filled")
    hold on
end

fig = figure;
%pos = fig.Position;
%files = dir('cast*.gpx');
for i = 1:5 %length(files)
    %filename = files(i).name;
    %route = gpxread(filename);
    route.Latitude = rand(10,1) + i; 
    route.Longitude = rand(10,1); 
    geoscatter(route.Latitude, route.Longitude, 50, "filled",'DisplayName', string(i))
    hold on
end
