How to use and edit rows and values of a data tip when created by mouseclick?

I want to add a third data tip row, (Index, Value, and new option: filename) for datatip points that shows the filename of the point selected. I already have an array that can be indexed to access the filename at a certain index.
I am trying to make the datatip points use the index value of the data tip point for logic to assign the third row to be the filename of where the data is coming from.
How do I get the values (x,y) of the data tip that I just created by clicking the mouse?
Can I use the values of the data tip that I just created to assign a 3rd value to the already existing data tip?
Thanks.

% Adjust as per your requirment
% Example data
x = 1:10; % x values assumed
y = rand(1, 10); % y values assumed
filenames = arrayfun(@(n) sprintf('file_%d.txt', n), 1:10, 'UniformOutput', false); % filenames assumed
% Plot the data
fig = figure;
plt = plot(x, y, 'o'); % Using circular markers
% Create a new data tip row for filenames using the custom function
row = dataTipTextRow('Filename', @(xVal, yVal) filenameFromX(xVal, x, filenames));
% Attach the new row to the DataTipTemplate of the plot
plt.DataTipTemplate.DataTipRows(end+1) = row;
% Create a custom function that maps the x-value of a data point to a filename
function name = filenameFromX(xVal, xData, fileNames)
% Find the index of the closest x-value in the xData array
[~, idx] = min(abs(xData - xVal));
% Use the index to get the corresponding filename
name = fileNames{idx};
end
