How label data points using text within a for loop

I am trying to produce a map of tide gauges using Geoscatter and then label each tide gauge with its corresponding tide gauge number. I have an array, A, that contains 58 tide guages - each one with it's own tide gauge number. I also have arrays for longitude and latitude that corresponds to each tide gauge number. So far, I have got this:

load('A.mat');

load('PSMSL+ERA5IB.mat');

geoscatter(Latitude(A),Longitude(A),20)

for i=1:58

text(Longitude(A(i)),Latitude(A(i)),string(A(i)));

end

This produces a map, but doesn't give the labels for the tide gauges. I'm not sure why

It seems that you have to create a custom data tips...

rawData = table([-13;-30], [-39; -39], ["ID 1"; "ID 2"], 'VariableNames', {'lat', 'long', 'label'})

rawData = 2×3 table
    lat    long    label 
    ___    ____    ______

    -13    -39     "ID 1"
    -30    -39     "ID 2"

figure
h = geoscatter(rawData.lat, rawData.long);
h.DataTipTemplate.DataTipRows(end+1) = dataTipTextRow('Label', rawData.label);

datatip(h, -13, -39);
datatip(h, -30, -39);
