Hello!! help me

[facundosala]

Hello. I'm not very knowledgeable about this, but I'm using this application for a personal project. I communicate with this app using the ESP32 to send notifications as it's developed. It works perfectly for me.
My question is how to also add messages from the ESP32 to the app to be able to command actions such as: Play, Stop, Pause, Next, Previous. I would greatly appreciate this information and anything else that could be useful to me. Thank you very much.

Copy video link of my project. From minute 3 you will see that I receive WhatsApp messages and also the names of the Spotify music that is playing: https://www.youtube.com/watch?v=D4dG4L-1KOU&ab_channel=FacundoSala
