The below given code is automatically popping up the figure attahced (2.png). I want this figure to appear on the left UI Axes (1.png) superimposed on the existing image instead of just popping up separately.

[~,~,NR_wells] = well_finder(I_final,2);
  hold(app.UIAxes,'on')
    for c = 1:NR_wells
        rectangle('Position',[newC(c,1)-HB,newC(c,2)-HB,HB*2,HB*2],'EdgeColor','y','LineWidth',3);
        app.ROI(c,:) = [newC(c,1)-HB,newC(c,2)-HB,HB*2,HB*2];
        app.Well{c} = imcrop(I_final,[newC(c,1)-HB,newC(c,2)-HB,HB*2,HB*2]);
    end
   hold(app.UIAxes,'off')

Try the following:

[~,~,NR_wells] = well_finder(I_final,2);
  hold(app.UIAxes,'on')
    for c = 1:NR_wells
        rectangle('Position',[newC(c,1)-HB,newC(c,2)-HB,HB*2,HB*2],'EdgeColor','y','LineWidth',3,"Parent",app.UIAxes);
        app.ROI(c,:) = [newC(c,1)-HB,newC(c,2)-HB,HB*2,HB*2];
        app.Well{c} = imcrop(I_final,[newC(c,1)-HB,newC(c,2)-HB,HB*2,HB*2]);
    end
   hold(app.UIAxes,'off')
