How do I get rid of custom data tip?

I have this script which adds a custom data tip to my scatter3 graph :
function txt = displayCoordinates(~, info)
global clickedCIE_L clickedCIE_a clickedCIE_b;
clickedCIE_L = info.Position(3); % 69
clickedCIE_a = info.Position(1); % -56
clickedCIE_b = info.Position(2); % 46
Hrad = mod(atan2(clickedCIE_b,clickedCIE_a),2*pi); % 2.4539
hueAngle = Hrad*180/pi; % 140 degrés
chroma = sqrt(clickedCIE_a.^2 + clickedCIE_b.^2); % 72
txt = {sprintf('CIE L: %.0f', info.Position(3)), sprintf('CIE a: %.0f', info.Position(1)), sprintf('CIE b: %.0f', info.Position(2)), sprintf('CIE c : %.0f ', chroma), sprintf('CIE h : %.0f °', hueAngle) };
end
It works great, producing this output :

Problem is, this custom data tip does not have any handle I can see? So I can't make the data tip disappears programmatically when it is no longer needed? Suppose I click on the pushbutton 'Plot2D' : I wish there was away to delete the data tip....
Any help is appreciated.

If feasible, you can store the handle to the DataTip when it is created (Option 1 below).
If not, you can find it using findobj() (Option 2 below).
Then delete() it.
h = plot(1:10);
h.DataTipTemplate.DataTipRows(1).Label = 'Custom X';
h.DataTipTemplate.DataTipRows(2).Label = 'Custom Y';
% Option 1: store the handle to the DataTip when it is created:
dt = datatip(h)
% Option 2: find the DataTip after it is created, using findobj():
dt = findobj(gca(),'Type','DataTip')
% now that you have the handle, delete the DataTip:
delete(dt);

Well, maybe try putting these lines:
dt = findobj(gca(),'Type','DataTip');
delete(dt);
Or more succinctly:
delete(findobj(gca(),'Type','DataTip'));
wherever you want to delete any DataTips from the current axes, and see if that works.
