Python subplots with buttons? Click event?

Question

What I would like to do is plot several signals at once and approve them in the eye, for that I wanted to click on the ones I want to approve and select them.

Make several plots side by side with the subplots, and I wanted to select with clicks only a few to get their index, for that there could be some kind of click event on each one or a button on top of each one, does anyone have any idea how to do this ?

I found examples of adding a button to a single plot, but I wanted an individual button for each plot of a subplot.

An example would be this checkbox on top of a plot:

x = np.linspace(0, 5, 100)
y = np.exp(x)
  
# Plotting the graph for exponential function
def plot(checkbox):
      
    # if checkbox is ticked then scatter
    # plot will be displayed
    if checkbox:
        plt.scatter(x, y, s = 5)
        plt.title('Scatter plot of exponential curve')
      
    # if checkbox is not ticked (by default)
    # line plot will be displayed
    else:
        plt.plot(x, y)
        plt.title('Line plot of exponential curve')
          
# calling the interact function        
interact(plot, checkbox = bool())

Or those yes and no buttons next to a plot:

%matplotlib inline
import ipywidgets as widgets
import matplotlib.pyplot as plt

button1 = widgets.Button(description="Yes")
button2 = widgets.Button(description="No")
out = widgets.Output()

buttons = widgets.VBox(children=[button1, button2])
all_widgets = widgets.HBox(children=[buttons, out])
display(all_widgets)

def logyes(b):
    print("yes")

def logno(b):
    print("no")

button1.on_click(logyes)
button2.on_click(logno)

with out:
    plt.figure(figsize=(3,3))
    plt.plot([1,2],[3,4])
    plt.show()

But I wanted to do this with subplots, several plots side by side and each one with its button to do something, which in this case would be to get its index.
