Read a diagram plotted with Librosa (Python) and create (e.g.) an audio file from it

Question

I use the module Librosa in Python to make a "click-beat-diagram" to a song (.wav-file). Please read the short explanation on the Librosa-website here.

I use the following code:

import librosa
import matplotlib.pyplot as plt

#loading the music-file (wav)
y, sr = librosa.load("C://Users/Max/Downloads/example.wav", duration=30)

fig, ax = plt.subplots(nrows=2, sharex=True)

#plotting the diagram
librosa.display.waveplot(y_beat_times, sr=sr, label='Beat clicks', ax=ax[1])
ax[0].legend()
ax[0].label_outer()
ax[0].set_title(None)

This plots a diagram, which shows click-signals depending on the time. It looks like this:

My question now is, if it is possible to read out this diagram and for example play a sound every time a click signal comes (the diagram makes a spike)? That is, to make an mp3 file from this diagram, for example.

It would be very helpful if someone could tell me an idea how to do this.

Thanks in advance

P.S.:I know there is already a similar question, but it does not relate to Librosa and is also not so well understood by me.
